Title: How automatic randomize color/texture in Corona?
Post by: cecofuli on 2013-10-24, 15:57:49

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...

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.
