Dirtmap Workflow

[Chad Warner]

I know that if you use after effects, you can take the different passes and overlay them the same way you can with photoshop (screen, overlay, etc) so that would be one way to do it, but it means having to render multiple passes of multiple frames, which could end up being a big pain.

which could end up being a big pain.

 

Exactly... unless the Render Elements can be used directly... Anyone got experience with this? (I don't mean 'have tried it' but i do mean 'have found a workable solution in an efficient production environment')

Any tips or (thoughts on) strategies are welcome ,-)

nisus,

 

Look into baking the dirtmap to texture. I don't have Max 7 but allegedly.......

For anyone using XSI (not many!), I've written a small tutorial on getting Dirtmap to work inside XSI using both the pass method and the in-render lens method, including two presets to get you up and running with it quickly.

I'm only familiar with using dirtmap techniques in LW but is it the same principle of applying it as a shader?

 

I just apply the shader to the required materials and render as normal-no passes. Animation is not an issue this way.

Less control but no need for multiple renders of the same frame and then having to comp it all.

9 months later..... Production, if you have the time to properly camera map a complex building, assigning polygon selections and material assignments to at least 2 cameras to get the coverage, I'd say go for it. The time may be better spent just rendering the dirt pass and overlay/multiply in post, AE, Combustion, shake.....

Another option is using the Dirt in the diffuse levels slot/channel. All instances of the same Dirt for all materials (1-white = full & 0-black=black)...Arch materials, seeing you are a fan, try the intensity slot. This will incorporate the Dirt effect during the actual rendering of the animation for all frames, but may add more time to the render.

If I could I would at all costs Bake it on, though doing a full set of passes in the end is much more flexible, including the dirt pass.

Edit....Dirt effects reflections, dimming them anyway. and if you overlay in comp the areas that are white in the dirt pass can be brought down to an acceptable level by using a Levels Adjustment layer or even doubling up the reflection pass (if alpha masked) and multiply....end Edit
