[LVL ED] questions about level editor/new custom entities

[Exostalker]

Some questions that I have:

1) When I open my new custom entities folder in entities in level editor, most of them or even all of them are repeated in that entity list at least once. So for example there is:

plant 1
plant 2
plant 3
box 1
box 2
plant 1
plant 2
etc...

Why is that? I don't have multiple ent files created, each has only one.

2) Question about custom models and textures. If texture is in too high quality, which memory will it affect, CPU or video card memory?
Same about models: if it has too many triangles, which memory will it affect?
