Most efficient methods of rendering.

[irwit]

Hi all

Quick question regarding most efficient method of creating shaders.

I've been using procedural methods for texturing a lot of my work recently and am wondering what the best methods for this are.

Lets say I am using the same dirt map, for both some texturing ( masks etc), darkening of existing textures and finally using the same ao as a seperate render element.

Is it best practice to use the same node for all of these or would 3 separate vray dirt texture nodes with the same settings be as efficient.

This question also applies for procedural noises, textures, anything really.

Thanks for reading

(EDIT) could a mod please move this to the Vray for Maya render theory forum. thanks

One node will be faster, as the dirt texture will be computed just once. Same thing for the other textures.

Cheers Vlado, would making an instance of the node still count as one node and therefore render more efficiently. My hypershade can get pretty messy very quick when using the same node in multiple places.

Thanks again for the help.

Not sure about that one, I have to check (basically just export a .vrscene file and see how many times the texture is exported).
