Texturing a building with Bodypaint

[Dtox]

Go to cgtextures.com and download some of their images to use for a base.

Personally, I prefer to use photoshop to create the actual textures.
I start with a base image though and build up detail in layers that I name as grunge.1 etc..

It's really not that difficult to do, you just have to familiarize yourself with your tools.

Use the burn, dodge, sponge tools to change the colors of the texture you choose.
Just select the areas that you want to add grunge to, and use a mixture of photo elements and blend tools/layers.
The paint bucket is a great tool when you use it in all layers mode.

Nobody is gonna be too willing to sit here and walk you through it step by step.
Although it isn't that difficult, there are many steps to it.

If you familiarize yourself with photoshop, you'll quickly realize how to go about it.
Methods vary according to a persons preferences too.

Maybe if you show us an image of what you're going for we can give you some general pointers and suggestions.
But as far as telling you exactly how to do it, that's not really gonna be possible.
That wouldn't help you learn to do it yourself anyway.

Gather some photo textures/references and start doing some tests and if you have more specific questions you'll get better responses.

Thanks Detox!

Appreciate your reply!
I have been doing some textures in the past on Photoshop and stick it on the model per elevation, but i really want to move to Bodypaint and paint on the bricks, make it dirty as a 3D model...

You're talking about the "paint with bitmap" feature in Bodypaint.

I've not used this feature much.
I'm skeptical of the amount of control you have over the resulting image with it.

What I know is that it works like painting with a basic brush except that instead of color or image function, it paints an image you specify onto the surface.
It can also paint multiple channels such as color, bump, spec, etc.

What app are you working with?
Cinema?
Or are you using bodypaint standalone?

My advice pertaining to using the "paint bitmap" feature is to create the textures you want to paint with in Photoshop first so you can fine tune them before using the texture as a brush.

You can use layer groups to keep the different channels organized and easily differentiated.
So you'd create a color layer group, then use that as the texture to paint the color on the model.
Same for bump and spec.

I'm a fan of baking textures myself.
You could bake a basic texture with an occlusion layer, load it into BP and paint on layers above the baked map.
Collapse it once your through painting and everything you painted becomes part of the baked material.
This has alot of advantages, the best being that your occlusion pass is now baked into the texture and will reduce your render time since it doesn't have to calculate occlusion at render time.
It also allows you to see where the occlusion is on the texture so you can paint accordingly, it also allows you to blend the occlusion better with layer blend modes in PS or BP.

I know the idea of painting directly on a model in BP is enticing, but it isn't as great as you think.
You'll have more control doing it manually.

Keep us posted on your progress.

I’m using Cinema 4D & VRay.



I loved baking my textures before, but since I moved to VRay, it’s not possible anymore.



What I normally do is to save the elevations, and then paint it all in Photoshop. I just thought there might there be a much easier way to get awesome textures done in BP….
