Unexpected Behavior With Textures
« on: January 15, 2024, 05:23:43 pm »
I've been experimenting with textures and sometimes Anim8or does things I'm really not expecting.

Is there a max (or optimum) file size (Mb) or image size (A pixels x B pixels @ C pixels/inch) for use as a texture? I've loaded a couple of (admittedly hi-rez) textures and Anim8or just quits. Is that to be expected? For the record I'm using Photoshop Elements 2021 to create/edit my texture files.

Having difficulty with bump maps. Again is there a max or an optimum file size or image size or resolution?

Finally, I've loaded a crap ton of textures into the current project. I'd like to be able to delete some of them. Can I do that? And while I'm at it, is there a way to delete unused/no longer used materials?

Sorry to be such a crybaby.

Observation: Using textures is really cool. GENERATING those textures can be a royal pain. (funny how the universe works that way, huh)

the optimal resolutions are binary powers, e.g. 1024 x 512 will work well, but 1000 x 600 will get resampled and won't look as good.  iirc the max resolution that can be handled is 4096 pixels in either dimension, larger than that won't load.  not sure if there's a Mb limit too.

can't comment on bump maps specifically as i haven't used those so much, but the same general rules should apply.

on the question of removing unused textures, i was going to say you can work down the list in the Texture Selector window and hit 'Delete' for each one, and it should warn you if you try to delete one which is being used anywhere in the project.  however, i went to test this just now and it happily deleted everything without giving any warning, which i think is a bug - @Steve there should be a 'there are references to this texture' warning, right?  or am i losing the plot?  build 1402 fwiw.

What I've noticed about using bump maps is that to make it work I have to select all the faces I want to use the bump map on and then apply the material with that texture in it. otherwise if you just select the mesh and apply a material with a bump map it gets really dark.

I've gotten good results with 1440 x 720 bump maps.
