Automate material change and rendering

[intenta]

I need to render a scene 30 times by changing only the floor material ... is there a way to automate the whole process?
Thanks!!!!!!!

Not sure what you are changing, but material parameters can be animated so you could render it as a 30 frame animation. If you are changing just hue, or reflection strength, etc. that should do the trick. If you are changing bitmaps, that might be more complex - you could (have never tried so just thinking aloud) use a layered shader and animated the blends on each frame to use a different bitmap. Alternatively, you could create 30 copies of the floor, each with a different material, and animate which floor is visible in each frame.

You could use the native Cinema Takes system for this  - set up each take with a different floor material and then you can "Render all Takes to PV" from the Takes menu.
