You could add an extra light parented to the cornea so it follows along, then set up a light link so that eye-shine light will be visible on the cornea but nothing else in the scene.

What is the best way to deal with this problem?

I created a bunch of armor/clothing on top of my character. Is there an easy way to make these things deform with the character without clipping? If not, is there an easy way to attach their meshes to the character without having to change everything?

So I haven't found a clear example yet. In AdvanceSkeleton5 for maya.

How would I add in extra joints for the breasts, belt, belt-ribbon, L_shoulder armor, Scarf and hair? In Rapid rig you just add auxiliary joints and for the hair new set of joint chains, easy pezy


The tutorial said it doesn't like models that are unsymmetrical. This will make the hair tricky but still doable.

>> No.666649

I'm assuming you are using Blender from the image provided... One method is to create a proxy mesh surrounding the clothing and weighting that to the armature you are using, then bind the clothing to the proxy with the Mesh Deform modifier. You can also use the Surface Deform modifier to directly bind the cloth to your body mesh, though I don't know if it is intended to be used in such a manner, it gets slow.

Select the right bone, go to the weightpainting mode and change the weights of the belt vertices manually by selecting them first (L) and weight painting them.
Also maybe there is a function that projects the weights from lower mesh to upper mesh, but I never tested.

>Also maybe there is a function that projects the weights from lower mesh to upper mesh, but I never tested.
There is, I think it's somewhere in the header options. Also the Data Transfer modifier may do the same.

The problem with this method is that if the topology of the clothing differs too much from the underlying mesh (and that is more or less a given) there will almost certainly be parts of the body poking through the clothing when deforming in certain positions.

Though now that I think of it this might work fine if you make use of the Mask modifier to hide areas of the underlying mesh obscured by cloth.

Just add more joints to the FitSkeleton. Add a chain of two for the breasts (A breast_joint and a breast_joint_end).

>> No.666775

>>666772
First off - each of those are disciplines in their own right. You can easily spend 3-4 years learning each one. You have to decide on one before moving forward. Buildings and furniture intersect to some degree (archviz), but otherwise humans (characters), nature props (env), etc. are more or less standalone with their own hosts of theory and technique that takes years to understand if you aren't planning on some meme low-poly nonsense but striving for AAA quality.
Don't hunt for these "workflows". Go learn how to use a 3D program first. Pick up the bare fundamentals, modelling, UV unwrapping, texturing, maybe rigging & animation. Then you can comfortably think about beginning to specialise and deciding on which field you want to do.
Fair warning: 3DCG is a lot of work. If you aren't willing to hallucinate wireframes on everything and have recurring nightmares about topology, give up now. It demands a ridiculous amount of discipline and determination.

>> No.666792

Well I have a lot of motivation for the moment but it's true that I'm not planning on making that my career or my main skill. I picked it up just because I wanted to learn animating. I might even specialize on that when I finish my current tutorial but modeling isn't that complicated for now. I didn't reach the organic modeling part tough so I guess that's where the complicated stuff will come. Same for texturing and all.

But I really don't plan on reaching a level that will make me get into the animation industry. I just want to be able to model a basic anime character and animate it in the end, that's the level I want to reach.
If can do that, I'll be more than happy.

If your instructor is teaching modeling, he mentions topology, and doesn't explain why and where it is important, seek a better instructor.

Anyway, this may be a good complement: https://gumroad.com/l/TepOz There's also https://topologyguides.com/ although it's not as well organized as a book can be.

how do you add edge loops to a hand placed set of vertices so that they're evenly spaced? i'm trying to make a human torso from the side by drawing it out using the polydraw tool in maya then multicutting some additional vertices if i feel like i need more detail. thing is i have to then make the loops manually with the multicut because edge loop tool doesn't respond. also smoothing doesn't work on the plane edge.

>> No.666948

if youre trying to bake info from a high poly to a low poly, you have to use the bake mesh maps, hence the ((mesh)). just select the model in the normal tab or the common tab i believe and then bake the mesh. i never baked info from high poly to low poly tho, i only do surfacing/painting.

anyways right now you dont have anything on the canvas. i cant really tell since you dont have the layers visible. to get info on there with say metal and roughness channels you have right here, you need to crate a fill layer specifically for each of them, because if you just have a paint layer with the channels active on the properties - paint, that means youre only painting with thats toggled on. with a fill layer you will cover the entire canvas with a color(B&W) that you can control with sliders. this will also allow you to put in textures when you mask it with a black and white texture image. then you can add a a levels to invert the colors depending on the mask you gave it.

the problem here i believe is that youre using this wrong, and are probably using the wrong shader to display opacity. if this is just for hair strands there is a great tut that you can follow.

I have a chance to upgrade to a new laptop, but I'm not sure if I should get the i5 8300H now, or wait and slowly save to purchase an i7

Figured I'd post this here since it kind of went under the radar in the Wip thread.

I'm not really sure how to go about making the hair of this robot, at all. I've tried a few different things, but I just don't really understand how to go about making a shape like it.
I've tried sculpting it, which is what I assumed I'd have to do, but nothing I did really helped. I tried starting with a sphere and going from there, but it didn't work. I'll be honest I've never really dived into the sculpting tools much, so I'm out of my element trying to do things with it.
If anyone has some advice, I'll greatly appreciate it. I just don't know how to start with a shape like that.

start with a plane, and add thickness with solidify modifier. it will help to keep things economical.
then when you have the base shape down you can start sculpting ontop.

you can even start with half sphere

i'm using an i5 4670 with an amd rx 480 8gb. if i have vray 3.6 rt utilizing openCL, how should my devices be enabled? the c++ is said to be for hybrid rendering with CUDA, so if it's on does that mess with openCL? and what does the amd accelerated device mean if i have my opencl intel runtime device? why do they both show up?

Is there a place I can get sets of pictures that show the deformation of the body as joints articulate? I know I can find these scattered around just by finding pictures of poses, but I was hoping there'd be something that shows specifically how deformation occurs in the shoulder from different angles and poses, and likewise for the hip, knee, etc.

How do you reset the zoom/view/whatever it is in blender 2.8? Like in 2.79, you could click on an object and hit period and it'd fix up any bullshit from zooming in too far or the camera rotating on a crazy angle. I don't know what that's called so I don't know how to find it in 2.8 since the key has changed?

Is there any particular sculpting tool I should be using? I tried using the grab tool, but it just seems like a mess and relies on the view angle so you can never grab things properly.

In Zbrush, how can I increase the mesh resolution on specific areas of my model like pic related?

I usually do this workflow :
>Sculpt in dynamesh
>Once I have all the detail I want, I start using zremesher and project details from the highpoly model
>I end up with a 4-5 subdivided model with lots of polygons, but I only want detail in specific areas like face of hands

The whole model is 1 single subtool. I cant separate it into different ones as it is 1 mesh. Any ideas?

I'm pretty new to 3D, I've only really used blender to fix models before printing them. Are there any good step by step tutorials you'd recommend for box modelling a low poly human male? I want to get good at building a basic mesh that I can rig, pose and sculpt on top of.

Nah, I'm pretty sure that's the HDRI. It uses square lights, so I think that's just the edge of one making that. There's not even a loop there (I mean there is when it's subdivided, but it's even so it shouldn't make a line like that). Where that light ends is halfway between two loops.
For comparison here's a few different HDRI's. I just had the other one originally because I liked the amount of light and the color tone.

>> No.668021

>>667849
if you want a higher geometry density to bake onto a higher pixel density without actually changing the low poly you can just use geometry HD downside to this though is i don't think you can export the hd geometry so the bakes from it would have to be inside of zbrush. the other way is obviously to modify the base mesh by selecting the edges you want higher density and subdividing them in another program this would require a little bit of finessing with topology though and youd have to reproject any details you've already made.

you do realize the index of refraction works only on objects that have volume right? refraction is all about how light is bent in that volume. keratin is opaque, its only reflective/glossy.

>> No.668063

and no nobody uses subsurface scattering for hair either. because again keratin is opaque. subsurface requires there to be depth in the surface where its starts to thin out like on the nose and ears.

It won't come out exactly like that, as that's probably made by hand via manually placing pixels.
But >>668045 is right.
It's a combo of all those factors and "thinking" in 2d to get things to look like that in 3d.You can probably get a good distance with a toon shader and proper lighting, after that it's mainly some creative post processing to try and look pixelated, after that you'd still have to go back in on something like Photoshop to manually fix things. There's no "one and done" solution, otherwise everyone and their mom would be doing it.
Honestly, you're probably better off doing the base shape/animation, then using it as a guide to make the pixel art by hand.

But judging by your response, clearly you knew all that, and had no reason to ask.

Totally wrong. IOR affects the Fresnel reflection even in opaque materials. Increasing IOR is like increasing specular, and very high IOR turns your material into a metal.

Are you braindead? The translucent properties of hair are what define the entire look.

no lol, like no shit it will effect it if theres no volume. but that IOR is ment for fucking objects with volumes you braindead faggot. theres a reason its called index of REFRACTION, thats why you need light to pass through to fucking REFRACT.

My guy, you can easily find humongous lists of metals and their IORs. Are you gonna tell me all those values are made up next?

In all honesty though, zero point arguing about this. The effect of IOR on non-transmissive materials (even metals) is practically imperceptible to the eye. Only nerds striving for scientific accuracy hunt for these numbers to put in their shaders.

It's fun to see what /3/ will argue about from time to time.

IOR, metalness,reflection and fresnel are not synonymous. you pretend like they are. theres a reason why you have maps for each of these fucking things. besides the fresnel thats just an effect that happens when the object has areas that are more reflective depending on your view. you dont map for IOR to fucking make it more metallic/rougher on specific areas, its ment for areas that have VOLUME in fact if you have a metalness map on your object you cant even adjust the IOR for metal/rougher values, just refraction.
