I am fairly new to appleseed and I am mainly using it in Gaffer. I wanted to try to play with the SPPM engine to render some caustics. I have created a simple scene with a ground and a simple glass model with thickness (using Solidify modifier) in Blender and imported it into Gaffer (version 0.57.0.0).
In Gaffer, I assigned an
asGlass shader with the following settings:
Transmittance Weight: 1
Here is how I assigned the shader just to be sure I am not doing anything wrong.
I added a directional light and an environment light to the scene. I then attached the
StandardOptions node to define the camera followed by the
AppleseedOptions node with the following settings:
Lastly, I attached the
Outputs and the
InteractiveAppleseedRender nodes and started the render.
This is the result I get:
I don’t think there is any problem with the shaders, as it looks to be working, so my guess would be it is something to do with the render settings, but I am not sure what do I need to do.
