Hi,
I’m on the latest versions of everything (3ds Max 2026, Corona 14, Forest Pack latest, Chaos Scatter installed via Chaos installer).
Even if I don’t use Forest Pack at all, just having it installed causes random crashes when I enable displacement in a simple scene (no proxies, no scattering used).
Even when usin 3ds Max 2024, or 2027
Steps:
Clean scene
Add material with displacement
Enable displacement → instant crash or viewport freeze
If I uninstall Forest Pack, everything works normally again.
Anyone else experiencing this? Is this a known compatibility issue with Corona 14 or the Chaos plugins?
Crash details (WinDbg analysis summary):
Exception: c0000005 (Access violation)
Fault module: Corona_Release.dll
Error type: INVALID_POINTER_READ
Crash occurs during geometry/displacement evaluation
Likely related to memory corruption or invalid pointer access in the rendering pipeline
System setup:
3ds Max 2026
Corona Renderer 14 (latest build)
Forest Pack (latest version)
Windows 11 (latest updates)
CPU: Intel I9, 13900K
GPU: RTX 4090, 24GB
RAM: 128 gb (4x 32gb, Kingston FURY DDR5, 6000Mhz, CL36. Frequency speed set to 4200MT/s)
BIOS: 2.22.1286 last update
Thank you.
