I've kind of given up on ever getting an orthographic projection option in LumenRT (ie. no camera - just pure plan view) - but the advised work-around from Bentley is to slide the Zoom in Camera Settings to the right and zoom out as far as possible.
This results in severely pixelated shadows and strange hatching bleeding over geometry where shadows should not occur. What can be done to resolve this? Quality Fast/ Standard/ Super fine makes no difference. Is it a GPU limitation?
While on this - when creating a Photo, why does LumenRT say "Exporting Animation" and "Frame 1,2,3,4 of 4"... it's not an Animation, its a single frame Photo.
Hello Max,
which graphics card do you have ?
will you please send me your test case so i can try to reproduce issue on my end
Thanks & Rg
Harshad
Hi Harshad - I hope you received the test case.
I'm fairly sure it's not a GPU problem - have just tried the same render with a RTX6000 and the result is the same.
Max
Thanks -
Yes, I use multiple monitors, but have tested with just a single monitor too.
Yes, NVIDIA is the default graphics card on my machine ("Use for Graphics and compute needs")
GPU usage with this LRT file is just 2,8 GB in idle mode, and tops out at 3.0 GB when I do the Save Photo - so I don't know what you mean by my "scene hitting 8 gb limit". Is LumenRT limited to 8GB? I'm using a 24GB RTX 6000 (as clarified in my third post above)
Could you send me your render in which the shadows are working on your system? I'd like to know the specs that make it work at your end.
On the trees issue - are the trees billboarded for distant views? If LOD setting instruction is to hide leaves when far away then I would hope this gets revised in future editions - a few green pixels (leaves) would be better than a vertical white line (trunk).
on above thread you said you working with Quadro M4000 which is actually a 8 gb card
on RTX 6000 issue should not be there
Thanks - but if you had read my third post you would have seen that I've upgraded to a RTX 6000. Either way, the file is only using 3GB of VRAM, and not "hitting the 8gb limit", even on my old M4000.
I get the same quality render for images as close to the subject as yours - but have you tried "P3 of 4" in the Photo strip? (as per my second post).
I totally agree with Max. The "evergreen" trees that have needles for leaves appear dead when viewed at a distance that triggers too much reduction in LOD.
This is unacceptable!
In the real world a forest doesn't die if it is viewed beyond a certain distance, so it shouldn't happen in LumenRT.
Please develop an improved method for handling changes in LOD for trees that have needles for leaves.
Hi Harshad - please would you answer my request for the specs on your system that make the shadow work? I've clarified that the problem is still present with my RTX6000 card, but you say it does not occur on your system. Please let me know what specs would make it work.
Thanks,
