Resize of StaticMesh using C++

[SvarogZ]

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.
