Hi, I try to render a scene with directional light. However, using mlt integrator, the rendering results have many noisy points under certain light directions, as the figure I show below.

The mitsuba log shows "Encountered a path that could never be mutated!".

I also try 'direct' and 'pssmlt' integrator to rendering the scene. However, only black images output.

The aim is just rendering the scene with directional light with mitsuba. could you please provide some suggestions regarding that?

Could you please give me the address to download Gaps? I can't find the website. Thank you very much!

Hi @yindaz ,
I encountered following error when running the scn2scn binary. Do you have an idea what is going on? Thank you!

Hi, yindaz, thanks for this awesome repo, I'm using it in my project.

I got some error when I run the example demo. My script is as follow. I download the camera info and unzip to projects_camera folder before that.

"python mitsuba_render.py -s ./rendering/projects_serialize/0004dd3cb11e50530676f77b55262d38/main_template_color.xml -c ./rendering/projects_camera/0004dd3cb11e50530676f77b55262d38/room_camera.txt -o ./projects_render/222/ -g ./rendering/projects_camera/0004dd3cb11e50530676f77b55262d38/room_camera_good.txt"

Hi @yindaz,
Thanks so much for releasing the code of your impressive work!
I am wondering if the link of Gaps module repo is missing?

Best,
XH

Hi, I am trying to prepare 3D models by using mtsimport.
I found that the code you provided contains mitsuba, but does it contain the code of collada? I was failed to build mtsimport from the downloaded .deb files.

Hi,

Thank you for your work.
The link to the PBRS project seems to be broken now.

Thanks for sharing the code. After I run 'demo.m', I found the rendering results are noisy. Is that due to the low resolution (640*480) or the setting of mitsuba? How can I improve the quality of the outputs?

Hi,

can you give some information about the file format for the room_camera.txt files?

Thanks!

First, thanks for this awesome repo, I'm using it in my project.

Is it possible to get the semantic volumetric ground truth as sscnet? I found there's no correspondences between these two projects (i.e. for the rendered image here, I can't find its corresponding volume).

Thanks for your help.
