I am having a weird problem where the light that is actually entering my scene is extremely over exposed even in filmic while the HDRI appears dim even though it is a 32 bit exr. I don't entirely understand what is causing this but I am wondering if there is either A) a setting where I can just boost the apparent brightness of the HDRI without increasing the total light entering the scene, although it would break some rules to do that and this is probably the most unbiased render engine I know right now; Or, B) if this is a bug that might need to get worked out; Or C) there is a setting that might cause this?
I have clamping off and this is obviously just one light group but I want to isolate the problem as this is visible in all renders. As a backup I have Object IDs on the windows and can combine that with the inverse of the alpha and fix it in post but since I don't have a whole lot of control over transparency of the windows with the alpha anyway I really want to get as much right in render as possible and something is just off about that.

Look like your Hdri gamma setting is too strong. Normally normal gamma 1 don't do that.
My gamma is actually lowered to 0.9 to wash out the image a bit and kill off some contrast and then boosted the exposure to 1.5. The problem is if I go lower than that then it washes out the scene too. With 1.5 exposure on a bright HDR with a lowered gamma is surprised the whole sky isn’t rendering as a near white blob. I have tried a few different IBLs and I am running into the problem on all of them even in other scenes. It is very strange. Everything gets very blown out And even clips but the sky is clamping at like 80%.

What is your blendluxcore version.daily build. If it is 2.5 test 2.3 or 2.4.
I have been in 2.4 since it was released at the end of last month. I’ll experiment with a daily build also but I have a feeling this a more of a circumstantial issue on my end so I suspect if that fixes it it will be more of sure luck than anything.
Here is the file. I simplified the scene quite a bit and I am sitll having the issue but admitidly not as bad. I went back to the original scene and checked my normals and everything and thats not a problem. My DSLR is set up to shoot log and even still in a room similarly lit even now at sunset, everything out the windows almost white it is so blown out while the inside of the room is barely affected. In the instance of luxcore here, it feels the oposite, the clouds corona and even sun do not quite look like they are clipping white but the light cast onto the floor is almost brighter than the HDRI it's self. This may all boil down to color management in the end on my part, but even still something looks just off to me about how much light hitting the floor is just as bright if not brighter than the content in the windows. The problem I am facing while trying to remedy this is if I bring the dynamic range down then A) the highlight on the floor gets brighter too, and B) the colors get really saturated which is inacurate.
