Problems with bump map.

Unfortunately, I think you might need to upload your blend file and package file so someone can take a look. You can try using 7-Zip, WinRAR, or Winzip to reduce your file size. That might help your upload speed.

Yesterday, I saw a post where someone was getting weird spots on a car they made and it was because they had not included mipmaps when saving their DDS files. I don't know if that's the case with your item.

In screenshot 502, is it just me or do you have vertices stretched out of place in your UV map? Again, it would be helpful to look at the actual blend file.

In screenshot 21.04.21_13-51-16. Are you seeing that in Blender or just in the game?

The extra texture you're seeing in Blender that came from the old model shouldn't be an issue as you aren't exporting textures when you export your finished blend file. You could delete that extra material in Blender if its presence bugs you for some weird reason, but I can't see how it would affect anything. I can show you how to remove the texture if you want but again, I doubt it's affecting anything.

Screenshot 516, where you ask about the image arrangement. It doesn't matter what order your resources are in the warehouse section. What matters is that you have all the resources your item needs.

Screenshot 502, where you ask about the vertex group, "transformBone." Let me explain a little what a rig is. A rig is what's needed for animation to take place. You can think of a rig as a skeleton. When you assign weights (Weights are also called joints or bones or vertex groups. It's all the same thing), you are assigning parts of your mesh to parts of the skeleton. If we were talking about a sim and you had made a shirt, you would want the elbow part of your shirt to be assigned to the elbow part of the skeleton (the rig). With me so far? Here's a picture of a rig for a character. The rig has "joints" where the character's joints are because a lot of movement takes place at the joints, just as a real-life body does.


Here's a rig for a dog:



Even objects can have a rig. Especially, if the object is going to be animated. in the case of an object, the rig most likely won't be shaped like a human. It will, however, have joints where movement takes place. Here's a rig for a toolbox:



The weird thing is, even non-animated objects have a rig in the Sims 4 (probably all games are like this). I don't know why. Maybe the developers thought it was easier to code the game that way. Anyway, non-animated objects have just one bone--remember, bones are sometimes called weights, joints, or vertex groups--and that bone is "transformBone." Yes, you have to assign your mesh to that bone even though your mesh will not be animated. The bone is part of the rig and every item requires a rig. You don't need to do anything with the rig itself at all. Just assign your mesh to the bone. Let me know if you need help with this but I think you did this part correctly. I'm not sure the item would even show up in the game if you had messed this up.

Is this the item you cloned?



It has four mesh groups, two of which are for the floor shadows. The other two are for the glass part of the table and the wood part of the table. The shadow mesh has just one mesh group. The floor shadow meshes have been deleted and the mesh responsible for the glass part of the table is gone, as well. This is why the shadow meshes have a lower polycount. The shadow meshes are responsible for the sun shadows, by the way. They only affect the shadows you see when your object is outdoors. The floor shadow meshes (drop shadow) are what the game uses for indoor shadows.

I don't think anything I wrote above is going to help you with your texture issue, however. Mipmaps will affect things, but only when your camera is zoomed away from your object. The game will display a smaller version of your diffuse texture when your camera is zoomed out. I just don't think anything I've written helps your issue but hey, you learned something new, right?

Please, please share your blend file and package file. If you don't, all anyone can do is make guesses.

There is one thing you can check, however. Do you have laptop mode turned on? What about the rest of your game's graphic settings? Are you seeing these weird texture problems in other objects?

Looking at the pictures you provided and going on threads that I have seen with similar issues in the past, I believe that your issue isn't being caused by the bump map texture at all. The issue is the model itself.

The car model is far too high poly for the game. Any time I have seen this issue in the past it was caused because the model used was above 10,000 polygons. When the people who were able to, reduced their models to lower than 10,000 polygons the shadow problems went away.

10,000 polygons seems to be some inbuilt limit for meshes in the game and anything above that breaks the way the game handles shadows.

Sorry to be the bearer of bad news.

Oh Wow!
I just looked at your mesh in blender. It still has the entire engine inside the bonnet!
You can delete that to begin with right away since you will never ever see the inside of the bonnet in the game. That should bring your poly count down a bit. There are SOOO many details meshed onto the car that if it were an EA item would all be done via the bump map or diffuse map instead.

My only advice mesh wise, if you really do want to get this car in your game, would be to remove everything that will never be seen in the game. There really is no need for the floor mat to have individually meshed grip ridges, for example. And you certainly don't need the internal workings of the door hinge and locking mechanism to exist at all.

I can't see what is causing the other problems though so can't help any further I'm afraid.

You are right, I took the car that I had made for lod 1 and it has even fewer polygons and now it no longer has the weird shadows on the body.Now I can continue working and delete a few unimportant things on the car.

Wow, thank you very much.
I have a lot to try out there.
Where do I insert the mipap? Or is that together with the texture?

I started all over with a new car, also in terms of quality, because I think it's great, also with the great textures.
Although it is the same car. It's just a little more sporty.
And with this car I don't have any problems with weird shadows on the trunk and the window panes.
I don't know why, but I've documented every step for myself.

I'll try the days with the mipmaps and the other steps in the blender.

Thank you so much for your help.
It has already helped me so much.
Thanks for your time and effort.
