I have been write my own volumetric shader using the material editor,and the material domain have to be the unlit,then i found that i can`t get any energy from the indirect lighting like the new lumen system.I hope to get lumen intensity while raymatching,but the hole lumen system are directly write into the DeferredSceneRendering::Render() function.If i want to get the Lumen Intensity in my volumetric VFX i have to change the source code,which is unacceptable.Is there are anything that i can write my own Shading directly in my project?I hope Epic rewrite there hole engine system as quick as possible.Who else knows that how many features will be add in the future.It will make the hole system swollen
