Hi,
Problem with the creation of a material to a tree with an alpha channel.
MODELER
1 - Creation of a rectangle
2 - open area editor
3 - Edit node
4 - Adding texture image Octane one - Loading image
5 - Adding texture image Octane 2 - Loading image
6 - Adding Texture RGBSpectrum
7 - Octane Mix Texture
8 - Octane diffusion Material
9 - Octane UVMap
10 - All nodes connected except UVMP
11 - Open, select cubic mapping and click on UVMap autosize
12 - Crash

I send you file by DropBox

Thanks in advance

In case Juanjo is out all weekend: try giving your model an honest to god UV and try again. See if it crashes after that. (you only use that UVMAP node when you do not actually have a UV in model).. and then try tripling (Shift+T) it too...

Edit: Sorry, I created a paradox there.. make UV and then test UVMAP -- not sure what I was thinking -- sounds like everything ended well though...

Hi and thanks !
Have you node example for making material with alpha layer ?
Thanks

Just plug a 24bit b/w image to Opacity.. that should do the trick bro.

All is good !
Thanks very much

Thanks for report this problem. Yes, there is a bug in the UVMAP node: if you click the "Autosize" button in Modeler it crash. Perhaps some of the tools needed for the Autosize functions are not avaliable in Modeler, only in Layout.

I will try to fix the problem for the next release. Meanwhile you should use Autosize only in Layout.

The UVMAP node crash in modeler is fixed for the next release. Now "Autosize" works inside Modeler without problems. Thanks again for report the problem.

Thanks to you !
You work hard on this app and it is very reassuring for the future.
For once someone was seriously invested in LW
Only problem for me and the type of project I'm working on, is the purchase of a Titan. But I think it will be quickly amortized.
Thank you again and good Sunday
