Hi,
I experience very slow nodes in a material when I use composite texture in combination with triplanar. I'v included a zipped C4D file in the attachment.
If you would place a new RGB Spectrum node in the material, and after that delete it. I experience a lag of 12 seconds (sometimes shorter, sometimes longer).
If I remove the triplanar nodes from the material, there is no lag anymore.
Is the lag also occurring on your end?
I'm on Octane version OctaneRender Studio+ 2023.1.1 (13000100), and octane standalone 2023.1.1 on Windows 10. Computer specs in signature.
