Formfont trees transparency mapping?

[woojojoe]

I am a Formfont subscriber and often uses their trees with transparent mappings. They look okay in Sketchup but when I tried to render it in Vray, it shows all the polygons without the trasnparent mappings.

How should I set up the material so the transparent mapping works for the formfont trees?

Thankyou! Any help is GREATLY appreciated!

Hello Woojojoe,

I'm also a formfonts digger...

Sorry to tell you that it is hardly doable with the current release of vray4su.

The actual material workflow ( vray material linked with su) doesn't recognize transparent texture map. (alpha channel informations, I guess)

You can do it with a real v ray material created from scratch, but you can't set up a correct UVW map ( because there isn't any viewer at that time).

For the time being, I suggest you to place your trees with a soft like Photoshop or Gimp...

Rumors tell that it will be possible to create material whith UVW map in the next release of VRAY ( soon I think, I hope,...I pray, I beg, I want, I ask )

Hope it helps and it is correct what I said

cheers
TOM

This is something that will be cleared up in the SR. The way materials are dealt with has changed, and things like transparent trees will be 100 times easier.

I'm not sure I understand the problem, but I often use my own 2D FaceMe trees made from png files with alpha channel transparency and I got them to work fine in VFSU (see attachment) by creating a clipmap in Photoshop (desaturating the tree image, reducing brightness, increasing contrast so it's a black and white mask) and loading it as the transparency map in VfSU's material editor.... or is it not working for you because of strange UV mapping in FormFonts trees? I haven't tried it with my 3D tree components so maybe that's the problem... I'm still a VfSU newbie.




p.s. I tried attaching an example and screenshot (43.2kb and 69.1kb respectively), but kept getting error messages about the upload folder being full and then that I have tried to post the same post twice. What gives?
