Once in a while, I see this kind of shading. Apparently it's called "shadow map", how do I do this on blender?

dirty vertex colors in vertex paint.

Do you know about Baking? You can bake Shadows if you want

And then there's all the sort of "visual interest" stuff like AO, using Poitiness node (and then bake that, since 'Pointiness' veries between high and low poly)

Anyway you can literally google 'blender shadow maps' on stack exchange or youtube and get more information

>>557342
sorry but this is not an AO bake...

>> No.557370

you only use shadow maps if you want to have a scene without light.
its possible to fake light as well.
>but why
optimization, mostly

>> No.557372

>>557370
ok but how is it done?
I like how it's rendered, looks better than the average ambient occlusion bake

>looks better than the average ambient occlusion bake
It won't look good in motion or in a lit scene. But anyway, I don't use Blender but in Maya shadow mapping is an option when creating depth maps. Maybe looking up depth map tutorials for blender will help you find your answer.

>>557372
you have an option in BI called "full render" when you bake. it outputs all possible light and shadow combinations.
personally i never tried it, because i like having my models interact with light in either realtime or other settings

>> No.557378

I have the answer you need. Pic related.

Basically, you're going to use a geometry node with the "Pointiness" value plugged into a color ramp. You're going to BAKE to a diffuse map in cycles (the bake takes a while). This will give you a great AO/Curve map/Shadow map. By adjusting the value of the color ramp, you can get more/less shadows.

Hope this helps.

can you even... read... in english...

the post... said... 'bake Shadows', then it said 'AO', then it also mentioned additional techniques like the Poitiness attribute...

please don't ever post here ever again...

>> No.557385

>>557378
that's not the solution at all.

pointiness value is meant for creating edge wear, not artificial shadows (altho dual purpose)
you can do what he wanted in blender internal,not cycles.

its all here

my bad. I searched for blender shadow maps and only got AO bakes or super old blender tuts. if i knew everything I wouldn't be here

the other anon suggestion was on point

>>557385
it worked perfectly for me, but it's great there are other ways to do something similar, thanks for the link

Is this for stone age engines that don't support normal maps or what?

It's just another map to use in your texture program. Sometimes valuable, sometimes not.
