Variations to instanced geometry and octane proxys Tweet

[Rik]

I've probably missed it but is there a way using max to apply a material to a bunch of instances and have various randomisation in the material?

I'm trying to do a tiled roof, the tile geometry is quite heavy so I'm trying to use instances or proxys.

In order to add some variation I'd like to:


have random rgb maps applied to the instances - eg, 4 images of rooftiles applied randomly to the different instances.
randomise the orientation of the rgb map images - ideally every 90degrees
randomly mirror the rgb images
have the different instances multiplied by by various shades of grey (think I can already do this one with random color into gradient into multiply texture, multiplied by the tile jpg. This creates variation but you can tell it's the same jpg over every instance and looks wrong)

I think you should be able to have 8 different variations(4 x rotation x 3 mirrored) with unlimited tone differences from just 1 photo of a roof tile.

For the Standalone Lua scripting guys I think they have a solution...

Am I missing something?

Hi Rik,
at moment, there is not something like multitextures in 3dsMax Octane plugin; as mentioned earlier we have to wait OSL.
Said that, take a look at this, it could solve your needs:
