I have some emissive materials that are not shown correctly.
It seems that the RayTracingObject BaseColor needs to be set manually
On my emissive materials the baseColor is black and only the emissive color is set:

Seems that the value then not gets applied correctly:

Hello there!

Looks like a very promising project.
Can you provide this as a Unity package with a package.json?
Would gladly test it out on my project.

I'm heavily using MaterialPropertyBlocks to adjust minor changes on materials.
See this here:
https://docs.unity3d.com/ScriptReference/MaterialPropertyBlock.html

When rendering with your TrueTrace these settings seem not to be taken into account:

In this case here I changed the UV scaling of the texture

Hey,

Getting this error+ a cascaded flow of random issues after it. Any clue what might cause this? Trying to run this on RTX 2080 laptop + Unity 2021.3.10f1.

There are more uavs (16) than the maximum supported (8) in ComputeShader 'RayTracingShader' kernel 'kernel_shade'.
UnityEngine.StackTraceUtility:ExtractStackTrace ()
RayTracingMaster:Render (UnityEngine.RenderTexture) (at Assets/Resources/RayTracingMaster.cs:803)
RayTracingMaster:OnRenderImage (UnityEngine.RenderTexture,UnityEngine.RenderTexture) (at Assets/Resources/RayTracingMaster.cs:908)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

This then turns into a bunch of issues, such as

ArgumentException: SetData(): Accessing 1980 bytes at offset 0 for Buffer of size 1800 bytes is not possible.
UnityEngine.ComputeBuffer.SetData[T] (System.Collections.Generic.List`1[T] data) (at <88d854ea2c91426ebc464f01cd71aa85>:0)
RayTracingMaster.RebuildMeshObjectBuffers () (at Assets/Resources/RayTracingMaster.cs:307)
RayTracingMaster.OnRenderImage (UnityEngine.RenderTexture source, UnityEngine.RenderTexture destination) (at Assets/Resources/RayTracingMaster.cs:905)
UnityEngine.GUIUtility:ProcessEvent(Int32, IntPtr, Boolean&)

Is this somehow related to some GPU's not supporting 16 UAV's or something?

Hi Pjbomb2 testing the Pathtracer, I tried to stack it with PostProcess and it seems to be applied after the PostProcessing. Would it be possible to render it before PostProcess ?

There is an FSR 2.0 PostProcess which gives significant frame rate improvements by upscaling. I use it in most of my projects and it would probably be quite useful to make the Pathtracer even more performant.

• I tried working with unity version 2022.3.4f1 with URP. Path tracing just didn't start
• I tried working with unity version 2023.2.8f1 with HDRP. At the start, I have a black screen and huge performance problem

There is no error in the console for both of them. Tried on DemoScene which came with package. Also all materials converted with unity's asset converter. I looked all the documenation but I couldn't found any solution.

And do you use mipmap? Don't using mipmaps, cause a weird view on textures. I attached a file for this.

I hop between machines a lot so I really notice the hassle of installing support for non-standard archive formats. 7zip - yeah. I get it. It can (sometimes) be worth it over zip files.

But rar? Really!?

Hello,

I managed to get it to work on my fully dynamic project.
All my meshes/models get created in runtime and it somehow works.

Some of the meshes though were not shown at first.
After playing around with the settings a bit I enabled/disabled "Enable Object Moving" and now I also see these models.
Even if it's disabled now. Perhaps some cache that got created? unsure...

Could you please upload a complete Unity project file? please

Hello,

in my project I can freely change materials of all dynamic objects.
How can I update the "Ray Tracing Object" to re-evaluate or recreate the information there to the actual new material set?

In my project I place every plugin/third party asset in assemblies and another subfolder. (i.e.: ...Assets\Plugins\TrueTrace)
Due to this the MaterialMappings.xml can't be found/created by your solution here.

Can you please create the file relative to the script that creates the file?
