Indigo Renderer Forum

I noticed in another thread that you can get the XFrog Sweet Birch model for free from TurboSquid. So I decided I would do some tree rendering.
In the process of making the render I've found several bugs/issues
I've also changed the way null materials work in order to make alpha mapping converge faster.

The leaf material is a diffuse transmitter / phong blend (then all blended with null for the alpha mapping)

I'll make a short tutorial for setting up this material as I think it's a core material technique that all Indigo users should understand

Wow, this would look even better with volumetrics

Gotta see that tutorial, maybe this would work for billboarded grass renders.

another one..

Time stamp? A new feature ? =P

yup

Nice !!!

Oh that's going to be very useful.

Ono, could you do me a big favour? This model is very simple. Too simple for realistic scenes. Could you try this with one of the trees here:

... and just repeat what you did (some of the trees do no need an an alpha map - a three-way blend mat - as the leaves are actually modeled, just a blend of diffuse/trans and phong).

I've seen some very serious slow-downs in rendering due to lots of leaves and am curious as to what you come up with.

nice.. I'll try the plum tree.

Are your leaves upside down by any chance?

They certainly don't seem to correspond to the branches in the images I posted, that's for sure

That tree's not that bad actually. But definitely one for the background. Looking forward to seeing what you come up to with these other ones.

This is the purple leaved plum.
Sadly the obj tris aren't divided up properly by usemtl elements, so I'll have to do some surgery on the obj first.

I used this one in my exterior times of day pic and it worked fine... Weird.

Did you use the .obj directly tho?

Ok, surgery done.
UV coords on the trunk looks kinda screwed tho.
