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.

Re: Filesaver hdr export half float?

Limiting the maximum float to 32bit range didn't work out. Maybe there are some nasty small floats, image editor can only show me 3 digits after comma 0.000, but 16bit limit is 0.000061. I will add 0.0001 to hdr map. edit The hdr map that was edited to 16bit float range was exported to exr unchanged...

Re: Filesaver hdr export half float?

Does the 32 bit float limit matter in luxcore in terms of what's on hdr map times gain?
I will check this next, gain down and use instead camera shutter speed compensation.

Re: Filesaver hdr export half float?

I see, thank you B.Y.O.B. I had it running for a 1 hour with classic and there is no black center visible. Maybe it's something with curved surfaces and too huge VM start radius. Shortest edge length in lens element is 0.000005476, i set the start radius to 0.000005476 and see what happens, classic ...

Re: Filesaver hdr export half float?

Removing 0.1 mm gaps didn't fix dark sun center, anyways this is easy fix in image editor.
Sun max brightness 65 000
path.clamping.variance.maxvalue = 159999996723281818181818181818
glass reflectance is set to 0.333
