Tutorial: Hard Surface Texture Painting

[Psyk0]

That's a very useful tutorial, thanks to Requiem2d and everyone that contributed!

Mind boggling. Thanks for this great tutorial! Will try it out if I can find some time this week (school )

And no, people aren't looking at you strangely wondering why you're taking a photo of a rust stain

Lol! I hate it when they do that. :P

fantastic tutorial and great workflow. thanks a ton!

Hmm no luck .. when I bake the AO (Ambient Occlusion) to texture all i get is a black map .. I made sure there was no overlaying textures and set the environment background color was set white . Global lighting level to zero.

In material slot .. gave the object a white diffuse color and added the Ambient occlusion shader to the reflection slot with a sampling of 16.

Then did a render to texture, told max to use existing unwrap, a complete map to be rendered into the diffuse slot, size of 512, output into source and then render .. but all i get is a black map .. can anyone help ? Thanks in advance

The way I do an AO pass in max is assign a standard shader>change its colour to white> environment to white>turn on light tracer>choose scanline as renderer>render to texture as a diffuse map>if you want higher quality change rays/sample to 500, filter size 2, bounces 1, initial sample spacing to 4x4 or 8x8 in the light tracer options. I always got better results that way rather than the MR/AO shader method. The black maps are annoying, god knows why that happens, just click the disc icon in the upper corner to save your map when rendered.

*edit* forgot to say the only light that should be in your scene is a skylight

^ Awesome thanks so much . I will try this out and let you know my results.

this has been very useful to me although im struggling with a few of the steps as they are a bit brief and dont explain in detail what you have actually done.. things like the specualrity (i have never made a spec map) part is very brief. what im asking is are there any other texturing tutorials out there that are of a similar standard to this one but explain what is done in a finer detail..

thanks in advance!

If you're going to do that, don't bake out the diffuse with a white material, bake out the lighting map. This way you can bake out a useful diffuse map instead.

thanks this is most excellent tutorial with many good advice

I was wondering what are the step in render an ambient occlusion pass in C4D 11?
