[tONy31]

Hi

I had a windows 11 update last night, started my machine this morning and Interactive Render does not now work in Vray also all materials show up black with no sphere... i have re installed Vray set it to default render and material.... reset the material slots... updated graphics card driver and its still not working ? i have tested on 3dsmax 2024 & 2025 both with the same issue. Corona works fine which is weird... has anyone else had this issue ???

Try reinstalling Microsoft Visual C++ Redistributable. A setup file is included in the V-Ray files: "C:\Program Files\Chaos\V-Ray\3ds Max 2025\utils\vc_redist.x64.exe".
