So I have a static mesh door in a blueprint to open and close, when I build the lighting the door is sort of too bright. It’s not exactly glowing but it is defiantly not supposed to be that bright considering it is in a dark location, attached a screenshot of the doors.
The lighting build is set to high quality and the mesh has a minimum lightmap resolution of 528, the mesh does have 2 UV’s with no overlapping.
It’s material only consists of a white base colour, 1.0 specular, 0.8 reflective. That’s it.
Does your door have some type of emissive material, or is it transparent in any way?
Hello xandan89,
What type of lights are you using in your scene?
Try unplugging the specular as well to see if this affects your door. Also whatever dominant light you are using in your scene/level, try increasing the indirect lighting intensity as well as the number of bounces. This might help the light bounce around in the dark areas a bit more so you doors are being illuminated properly.
If any of these suggestions don’t fix the issue let us know and we will investigate further. Thank you!
I have unplugged specular so there is only a white base colour left and that doesn’t seem to have changed anything.
I have also tried increasing the indirect lighting intensity and it did brighten the room however the doors still have their glowing effect.
No problem, next I would say try reducing the lightmap resolution to like 64 or something a bit smaller to see if this also fixes the issue. So take down the minimum resolution of the mesh to 64 and set its resolution in game to 64.
If you don’t want to change the minimum resolution try setting the lightmap index to 1 in your mesh as well.
If either of these do not work would you mind sending me a copy of your mesh with the material on it so I can further investigate?
So I have tried your latest tip but I have mixed results. In this image you can see the door on the left and far right is lit normally, however the door in the centre has the strange glowing effect.
If you would like me to send you the door and material how would you like the file? would you like the blueprint .uasset with the .uasset for the door and material? or the .uasset blueprint and material and .fbx door?
One more question before we get your stuff sent over, what type, and what values are the light that is in your scene set to?
Instead of just the door being sent…how large is your project. Because this problem might not be with your material or the mesh, but the lighting in your scene, we might just need the entire project to figure out a solution.
What you can do is either private message me on the forums and you can zip it up and send it to me that way. Or you can send the zipped file via DropBox which is pretty easy as well.
Thank you,
My light inside the blueprint is just a pointlight, I have attached an image showing the settings currently used on that pointlight.
My project is currently 4GB, as I live in Thailand the connection here isn’t brilliant and would take me far too long to upload.
Ok, you have a light inside of your blueprint for the door? Take that light out, because what is happening is that light is taking priority over the lights in your scene.
For the point light in your scene and not the blueprint.
Set the Min roughness = 0.6
Turn off Cast Translucent Shadows
Set the Shadow Bias = 0.85
Set the Indirect Lighting Intensity = 3.0
Set Source Radius = 0.0
This should help clean up your lighting a bit so you can start from there.
I hope this helped your issue!
I do not have a light inside the door blueprint, the light is coming from another blueprint which contains a mesh and is linked to some light switches placed in the level.
I will adjust the settings and let you know the results.
I have just tested out the latest settings and the result is still the same, doors still glowing.
So go ahead and send me everything associated with that door mesh so I can see how to fix your issue. DropBox is preferred. Thank you!
So here is a dropbox link to the files. It contains the .fbx for the door and door handle, the .uasset for the material and the .uasset for the blueprint.
So I downloaded the files, but I am receiving an error message because I have no parent class in order to open and view the blueprint of your door. However I did notice when importing your door mesh you have no smoothing groups? You need to have smoothing groups enables when exporting your meshes from your modeling software to have lights and materials appropriately display. This actually could be your issue.
Here is the error message I am receiving:
Oh, I will quickly re-export the door with smoothing groups and try rebuild the lighting and let you know the result.
Just rebuilt with the reimported door with smoothing groups and it is still glowing. I forgot to include the binaries for the door, here is a link to them:
I am still unable to place the blueprint in my level. Is this a C++ project because if so I do not have the class that it is referencing.
In order for me to assist you further I would need the Uproject file, the Content folder, the Config folder, and the Source folder.
This will allow me to open up your Door blueprint and continue forward trying to debug your project.
Thanks,
I currently had some issues with my PC and have had to start re-uploading the project again to Dropbox, this will take a while as I mentioned before my internet connection isn’t the best when it comes to uploading.
We understand. Do your best to make sure it is all there so we don’t have to repeat the process
