Hi guys, I’m really new to all this and im not interested in coding but in the visuals.
The thing is I made a house in Sketchup and divided it in diferent elements for then adding materials separatly in UE4. when I ported them, the first problem was that every mesh said “Invalid lightmap settings” so I readjusted every single element light map resolution. Is there something so I don’t have to do this?
After that when I tried applying materials to each static mesh, the textures were in a much lower scale, but when i add them to a static mesh made with a brush, the texture looks fine, anyone knows whats happening?
Did you provide a second set of UV coordinates for the lightmaps and assigned the correct channel in the mesh prtoperties?
Your texture UV maps might be overlapping and lightmaps require a non-overlapping UV arragement.
Can you show a screenshot of your static mesh properties (including the extended properties)?
Also a view of the UV sets itself would be nice
Yea, I just learned that by searching more in the forums, I didn’t set up any UV map, my bad.
So my question now is how to get the coordinates and everything right? Because im working on sketchup for the modeling
Hmm, I dont know sketchup…
As a tool of last resort (if you dont have 3dsmax or any other program that doesnt support UV unwrapping), you could use the UE4 mesh editor function of generating uv sets. I came to learn that they are not optimal and very basic, but should suffice in most cases)
For lightmaps you want to have another set of UV’s. So in the static mesh editor in UE4 click window then generate unique UVs.
Then in the button right on the generate unique uvs tab you can either create new or layout using 0 channel.
once you’ve clicked apply you might want to check what they look like.
On the tool bar at the top click UV, then clik UV channel and change it to channel 1 and you can see what’s been done.
This only works on meshes that aren’t to complex so if its really detailed it will most likely send you a d3dx message. If you see that then open it in 3D Studio Max or what ever other modelling program you’re using (I’m not sure if sketchup can do it) set up another UV channel with it all unwrapped with no polys overlapping each other.
Hi! Thanks for helping me out. I tried generating uv maps in ue4 but a pop up comes up saying “GenerateUVs Failed, D3DXUVAtlasPartition Failed.” no idea what it means. I will take a look into that sketchup extension and see whate comes up.
yup, the meshes aren’t too complex, or at least thats what I thought, but it gives me the d3dx message anyways so I will see on making the UVs in another program, any tip on that? does the program make it automatically or is it a manual process?
Which would require one to be enrolled as a student. As far as I remember, you have theo show them the paperwork to be eligible for this licence…
So if you are not a student, unfortunately you pay through the nose…
I tried blender once before but the ui put me off quite a bit. I actually use Cinema 4D for all my modelling and uv mapping, I mostly use 3ds for rigging and animation because its compatible with most if not all engines. To be fair though Cinema 4D does export fbx but 3ds seems to be more compatible with ue4, plus it has physx which is awesome!
The same here. When I opened 3dsmax for teh first time, i could make an object and move faces and vertices after 3 minutes…
With blender I could get nothing done at all without reading first. The UI is a masterpiece of counterintuitivety…
I prefer max, because and its good…
Come on, they made Toy Story with it
