hi guys,
how are you?
i have 3 Strange problem with UE4!
when i import a mesh in unreal engine,and create material for it mesh seem black in scene and i should to navigate camera and Approach it to can see model about normaly a bit.!(i think when i use from metalic!)
://puu.sh/7ZhTN.jpg
another problem is that u can see Strange material on mesh after building!(Spots and diffrent colors)
://puu.sh/7ZhWe.jpg
i deleted sample meshes in scene and you can see another type of bad materials in scene after bulding!
://puu.sh/7ZhZY.jpg
why i have these problems?
are bugs or i should to set things?
(for every model that i import to engine i see these problems!)
help
thanks
Make sure that your meshes have a 2nd uv channel with a proper lightmap + add a lightmass importance volume + type in a higher value at lightmap res (e.g 128): That should solve your problem with the strange black spots on your mesh
hi,
thanks for your help!
but some points:
1-i did not use from uv unwrap and i textured my model as uv map modifire in 3ds !
2-i did not set 2nd uv for lightmap!(because i have not uv unwrap and i use from uv map)
3-when i build mesh in scene i see this error:
://puu.sh/80upR.jpg
4-when i set lightmap resulotion to 128 for example i see like this:
://puu.sh/80uuS.jpg
and for better i should to set on 4!
a quastion?
sometimes,when i build scene my scene be orange!!!my sky changed to Afternoon i think!why?
://puu.sh/80uOv.jpg
i could to understand another thing!*
in this pic
://puu.sh/80uUg.jpg
you can see shadows of models in scene!!!
direction of directionallight is from right of the pic.!
and you can see right models of this model in scene:
://puu.sh/80uZr.jpg
is not strange?
because i think should not shadows of this models be so far and long!
for every model that is imported in engine,should i create for it 2nd lightmap channal?(i didn’t it in udk for models that was imported!)
help
thanks!
First of all, it is really important to get your UVs sorted out. I recommend that you go back to your 3D tool and have it create the UVs for you (a simple 3-plane unwrap or something similar should be fine for this test). UVs are a quite important part in the process and they can cause various issues when not done right (there’s tons of tutorials out there for tools like Maya or )
You don’t always need a second UV channel for the lightmap. But if the engine complains, you can create a second channel directly in the editor like this:
Double-click your mesh in the content browser to get you into the mesh editor
Go to “Window -> Generate Unique UVs”
Select “Create New” and make sure that “UV channel to sve results to:” is showing “UV Channel 1”

Click “Apply” (the rest of the settings should be ok)
Now go to the “Light Map Coordinate Index” option in the details panel and set this to “1” (= Use UV Channel 1)
://www.team-imx/images/UE4/lightmap_uvs_2.jpg
Save and close the mesh editor
Build
This shold take care of the lighting issues you’re having.
About the orange in the scene: Have you changed some settings of the skybox or the directional light?
this ways for solving my problem are orginal ways that everyone should to do these?or is a way to solve my problem?
i want to know why have i this problem?!
i found my problem for orange.(was from direction of directionallight)
new problem that i see is from all meshes!
see this pic:
://puu.sh/80zwZ.jpg
you can see strange material in floor of chairs!
when i Approach to them it be good and has not problem!problem is when i am far from them!
see this:
://puu.sh/80zJF.jpg
this problem you can see in Columns of top!
or
://puu.sh/80zM9.jpg
with problem in sphere and floor of it!
://puu.sh/80zOv.jpg
why?
“problems of unreal engine are very strange!!! in rendering!”
When you’re working in 3D and specifically with game engines, there are a few workflows that you need to establish, or you will run into problems sooner or later. Clean models and UV layouts are fundamental and need to be right. Take your time to do some tutorials on this - it’s worth it
Concerning your current problem: Have you bulilt lighting? Also, have you checked the lightmap resolution of these objects? If you get any errors, please also post those.
It is interesting that after any building i can see another shapes of materials of meshes on far seeing!
this scene was good and has not problem!i do not know!
my problems are very strange!
in starter map in new package created i see map that has not any problem!
when i build the scene again i see new problem in it:
://puu.sh/80IkA.jpg
why why why why???
and when i approach(near) it i can see good material:
://puu.sh/80Iv9.jpg
this is not just in editor and these shots are from the game!
why?
why everytime i have new graphici problem in building?!
Just to make sure I understand this correctly: You only get these arfifacts when you are at a certain distance and not when you’re really close up to the objects?
sometimes i have this,sometimes i have not this…
i this scene i have this problem…
in other sample scene i have this problem but just with black areas Instead Colorful problem!(this Colorful is not just seem!i can see sometimes for example just normal texture of mesh!!!(normal texture connected to diffuse!) or i can see a bad material of other mesh on another mesh!)
do you know what i say?
is very strange!
i think,i should to change my windows from 7 to 8.1!
my performance of system is good but i don’t know why i have these problems!?!
I wouldn’t recommend switching to Win 8.1. Its far less stable than Win 7, especially for high-end work. We had a ton of issues in the studio with Win8.
At this time, I would look at your pc setup, as mentioned. Could be a graphics driver issue or something related.
Can you post the graphics card you use, and the driver version?
thanks guys (IMX & )
: graphic card=>EVGA nvidia GTX 550 Ti
Ram=>8GB
cpu=>AMD phenom™ II x4 965 processor 3.40 GHz
windows:7 x64
no i think i have in all scenes and projects!
IMX:
yeah you say right!
my specs was as mentioned in up!
my driver version of graphics card i think is from 3 years ago about!i did not any graphics card update!is important?(new version is 335.23 in net)
Yes, it is very important to keep your graphics drivers updated! You can miss a lot of functionality, apart from having quite some issues when you use drivers which are that old.
I would definitely update them to the latest versions for your card and check if your issues in UE go away.
It is generally advisable to keep your drivers updated…
Let me know how it goes once you’ve updated your graphics driver.
