HI!
I have a BIG mysterious problem, I have a tree made on speedtree and exported in .fbx with its animation (MCC cache), and I don't know why but the needles are not rendering if its animation cache is enabled. But no problem for the bark mesh!
I can see my leaves with its animation in my viewport. If I unabled the cache, I can see them on my rendering (but they lost their animation of course).
No alpha either in the render with the cache enabled
Primary visibility enabled and no render layer, pb still there in a new scene
test made with another shader, same pb
no opacity map (aistandard shader with just a color constant in the color)
caches exported in the same time from speedtree > two folders (one per mesh), one file .xml and 1 file .mc/frame in each folder, the problem doesn't seems to come from the cache
If I try exporting my tree from speedtree in .abc (format HDF5 or Ogawa) I got a file of 11Go or more!
I am rendering localy (not on renderfarm)
I need to fix this problem really fast, I hope someone can help me...
My softwares:
windows 10, 32 Go RAM
maya 2019.2
MtoA 3.3.0
arnold core 5.4.0.0
I use Speedtree as well and stop using fbx animations. I use Alembic and it works without any issues. Also, it is faster exporting Alembic files.
How do you manage creating an epicea for a pretty close view? It was a big challenge for me, I used cards for blocks of needles but it doen't work for a close up view. That's why I got a 4 000 000 polygons model 😞
HDF5 is a common hierarchical data format, and several tools exist to view and edit HDF5 files.
Ogawa is an Alembic-specific file format available for use as of Alembic 1.5. Ogawa files are on average smaller (by 5-15%) and faster (4× for single-threaded reads, 25× for multi-threaded reads on 8 core systems) than HDF5 files.For pine trees, I actually used batched leaves. I got something around the 4 million polygons as well. For a close up you may want to create just part of the tree
Update:
I re-exported my tree from speedtree in .abc (format HDF5) and ... I got a 61Go file, but I was able to import it in maya (I thought it wouldn't working..!) and... I still got the problem :'(
If you apply one single material to the entire tree, do you see the needles? I use 3ds Max and I honestly never had that issue.
Can you export just one branch for me to try in 3ds max? Maybe just 2 or 5 frames.
here the .abc : (42 023 Ko, 5 frames)

It works fine here.
Maybe is the way he is importing the mesh. You used a Arnold Standin perhaps that is the difference.
Hi! I didn't used standin for my tests, @Lee Griggs I don't see the needles in your image and @Ciro Cardoso I don't understand why it works for you ! ^^"
Anyway, I used maya renderer, for my branches that will be in defocus it will be enough 😕
Thank you very much for your help guys!!
