Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Resize of StaticMesh using C++

The task is to change the size of StaticMesh from C++.

There is base C++ class. StaticMesh is choosed from BP class. I want to use the same BP for different sizes.

From Blueprints I can do it here (see picture). Is it possible to do the same from C++ for one copy only? Or advise the way to do it proper. Textures should not be resized.

Not Sure exactly what you want, why don't you simply scale the component ? (UStaticMeshComponent)

 UStaticMeshComponent* staticMesh;
 staticMesh->SetWorldScale3D(FVector(2, 2, 2));
 staticMesh->SetRelativeScale3D(FVector(2, 2, 2));

In that case textures on the edges are stretched also.

You could change the material so that the edges won't stretch.

Now i know what you whant, I would recommend you to do it in material to avoid having to manually code dynamic scaling.

Material has a TextCood node, multiply it with the object scale node and 'voila'

You should keep a correct scale ratio. but i don't think there is a magic solution for that case

Yes. Thank you.

I can't do exactly the same. I have to use one BP material.

There are 3 materials (one for opposite sides of a cube).

DataAsset contains size scale, material and other information.

Using C++ I can change any scale of the cube and adjust UVs in BP already.
