.ply file not generating particles in vfx graph #80

Open sushicab opened 2 years ago

sushicab commented 2 years ago

Hi Keijiro,

Im testing VFX Graph in the PcxEffect3 project file with my own .ply file. The .ply's container type was selected as Texture. Already connected position & color map to set position & color from the map but particles were not generating/ showing in the Inspector.

I'm suspecting the color&position map which my .ply file contained has some missing information. (the .ply was generated from .obj in meshlab by using Monrecarlo Sampling). The .ply could be presented & rendered perfectly when the container type was selected as 'Mesh' in Unity.

Would definitely be great to have your advice! Thank you very much in advance.

Unfortunately, no, I couldn't afford time for it.

The header probally has problem. My PCL library cannot read it.
