model takes too long in building light cache in a test rendering of exterior
What rendering program are you referring to?
There are lots of rendering applications out there. You need to indicate which renderer you’re using when you post. I moved the thread to the correct forum, too.
How long is too long? Please be more descriptive in what the render is doing. Maybe even upload a model screenshot and your vray settings.
it has taken close to 3 hours now and its just test rendering option i picked from the preset option. the only thing i change in the vray setting was just the environment- background option to an hdri map
Maybe upload the model as it’s hard to say what’s causing the problem.
To try to narrow it down, I typically start by doing a materials override render to see if that helps.
Then I try a render with different entourage groups either turned off or saved separately and then deleted and purged from model…sometimes a model from 3D warehouse, etc has a bad material reference that can cause problems.
Next, save a copy of your model and reset VRAY settings to default. That may help indicate there’s a problem with one of your settings.
Once those are checked we can try other things.
There is also no information about Vray version (1, 2, 3 or 3.6).
Could also be you computer / SU version / Graphics card issue. Do you normally have fast renders and only this one is slow?
