Hello guy, I have to create tons of rocks, with different colors: - I tried BerconGradient (crash when I try to change Type: Random) - I tried Multiscatter texture (not work) - I tried Multiscatter (CGSource ) Crash Well, I don’t want to create 10-20 different ID material with slightly color variation for 10 different rocks textures. Any suggestion? ---

As far as I know, all those maps use some kind of node ID to randomize stuff and corona is not able to use those IDs in the Shader atm. It’s already requested but I guess you will have to randomize it with a simple Script or something like that. ---

Mmm.. I think the same. As you know, there are some script to change randomly maps value? I’ve a multi/sub obj material, with 20 CoronaMTL inside, with ColorCorrection in the diffuse and the same diffuse texture for the 20 material. I would like to change automatically the ColorCorrection HUE ans the Saturation automatically, and not change manually for 20 sub-oject (for 10 different Multi/Suvb obj) =( EDIT: ZORB ---

Google multitexture and UVW random - plug and script! ---

Do you have Forestpack? If you do, you can make a material with Multiscatter Texture, tick “Use Object Color” and then control the variation in Forestpack Object “Color Tint” tab. ---

No, I haven’t. But Zorb script + Random Mass Script + Multi/sub Obj is enough (for now). I will wait the new Corona version 😉 ---

I am not a Scripter, but i did a little tool (To my use) that shuffle the MaterialIDs on a set of objects, so you can use multi-sub… ``` It's not perfect and it has some bugs, but they are easy to contour... If you want to check... ``` [http://www.kumodot.com/portfolio/kumotools-rnd/](http://www.kumodot.com/portfolio/kumotools-rnd/) ``` Or in ScriptSpot http://www.scriptspot.com/3ds-max/scripts/kumodot-rnd-tools ``` ---

ok, plenty of possibilities now ---

The possibilities may be unlimited but the tools are not. Just wasted a whole evening testing bercon maps with corona and found a devastating bug which lead to throwing the whole bercon crap into the garbage bin (RAGE!) . Multitexture is way too limited and the bitmap loading option is just fubar - honestly, who really likes to use that map O\_o?! If someone had some real alternative to randomizing a ton of maps/materials by scripting it would be great! ---

I miss This possibility very much too. So i will join the crowd. To me it is far more needed than fx. SSS. ---

A simple material modifier on the objects you want to use randon multisub map not work?! ---

I’m not sure but I think “Ky\_Color Variator” doesn’t work neither… Not sure if it’s plugin side or render.
