i have a big scene with many trees (3d) and i want to render it with fg+gi.

In some views my pc uses all memory and stops rendering.

Will render to passes help me?

Is there something that i can use instead of fg which is very slow?
i read something about ambient occlusion and dirtmap shader.

is there a way to plug into a shader's color a texture and dirtmap?

thanks
mike

Hi mike

You probably would benefit from Dirtmap to improve your performance.
You can get it here:

and Jeremy's 'toLight Shader Suite' might be useful too:

BTW:rendering out a seperate pass from it would also be a good idea ;)

thanks,

i saw in a tutorial that dirtmap occupies the color slot in a shader.

How am i going to benefit this powerful shader since i allready have a texture mapped as a color?

is there an explanatory tutorial somewhere?

Plug it into the diffuse attribute of your Maya Shader(incandescence slot will work also), or into the relevant diffusion slot of your MR Shader.

Does dirtmap work on MR Stand alone too?
