Re: problem with orthographic camera

Seems like orthographic camera scale of 10 is infinity times brighter, scale 1 is much better and perspective camera is perfect.
Switch the auto linear off first.

Re: bidir+metropolis

About that eye path depth. Lets say i need eye path depth of 20, can i still use default russianroulette.depth 3 and cap 0.5?
russianroulette.depth 20 seems to be 3-4 times slower.

Re: anisotropic metal UV problem

UV texture normal map, or physical mesh displacement should work.

Re: Struggling with LuxCoreGUI

The auto save is most useful feature of LuxCoreUi, if you must use that. Other than that, it's not very productive, for an example if you set the DLS C to use very high quality settings and DLS C takes 7 hours, then after 7 hours you get to insert render resolution, and you wait another 7 hours befo...

Re: Want to have a diffuse air inside a room and clear air outside

Can it be the bi-dir likes ray-marching that heterogeneous has?
Anyway here is heterogeneous with step size 0.5 and max steps 32 (almost like homogeneous in terms of speed).

Re: Want to have a diffuse air inside a room and clear air outside

Is the step count 1024 overkill for dusty room?
The step size of 1 meter is probably good speed improvement from 0.1 meter.

Re: Want to have a diffuse air inside a room and clear air outside

I don't know the volumes very well myself. If possible at all the homo volume with multi off is much faster than hetero. Maybe some other setting is wrong. The scene epsilon is worth testing. I have this other scene where rendering passes sample/sec gets lower and lower over time, but rays/sample do...

Re: Want to have a diffuse air inside a room and clear air outside

Seems like with the type of hetero scattering volume, the camera can see out of window. There are hdr and textures included, that's why 500 MB. https://drive.google.com/file/d/1_VwlnPSYP-7D_yHC1NXRbft-eELo06Tx/view?usp=sharing Window frame and glass is splitted in 3.
