Corona & large scenes

[Jpjapers]

Hi, I Love corona but theres one thing that really gets me a little frustrated with it. It doesnt handle large scenes as well as vray.
I have a massive scene. about 48 million polys. probably 500+ textures and hundreds of objects. Vray will start rendering within a minute of pressing render but corona takes about 5-7 minutes to do the translating and parsing. Are there any settings within the render settings dialog that can help with large scenes?

There are similar reports already so we will need to take a closer look. Can you check if you get better performance (also in viewport, if you are experiencing some fps drop) if you assign a default, fresh CoronaMtl to all of the scene objects (I do not mean overrides, just select all the objects in scene and assign the material to them).

Theres no noticeable change in viewport speed when assigning the fresh material but that could just be down to max having to draw all of the geometry (there is alot)

If you set small background items to display as box (Put them on a layer and set the layer to that is the easiest way to do it) it should help. Proxies help as well.

Same problem here plus others related to bump mapping. There is a problem in memory mangement?, win10 crashes with a blue screen....
