Mac freeze when clicking on marketplace skeletal mesh within editor

Hi, I bought both MilitaryCharDark and MilitaryCharSilver from the marketplace. I Downloaded them and added them to my project via the Library.

Whenever I select the skeletal Meshes anywhere in the editor (e.g. content browser -or switching an existing blueprint character’s default mesh to it), it causes the editor to hang and become unresponsive. It never recovers, and I have to force quit it.

I’m on a 13" 2013 macbook retina with 16GB of Ram. Apart from general mac stability issues (crashing in the event graph, etc) it generally runs very well, so I have no idea why it couldn’t handle showing/loading a 15k tri character.

Same thing happens when I try to load the example level for the models OR interestingly, any of its materials.

I’m using 4.6.1 - but also tried the same thing on 4.7.0 preview and got the same result.

I also tried loading them into new blank projects and got the same result. And I’ve verified the downloads, and tried adding and removing them from the project. Other things I’ve imported into my projects have worked previously (including the anim pack and extra textures from the marketplace).

To be honest, I’m having trouble tracking down where the logs exist on my HD. Was expecting to see something UE4 related in ~/Library/Logs … but nothing as far as I can see.

Looks like the materials and/or textures are the issue. Deleted them from Finder and the meshes load up fine (but completely untextured of course) now.

Ok. It seems to be the textures that are the issue. When trying to load or use the main texture for one of the characters, T_Male_D (diffuse?), the hang happens. It’s a 4096x4096 texture. As a uasset I don’t think there’s any way I can reduce or convert it, presumably.

My guess is the material access was freezing it purely because it was accessing the textures.

Any ideas anyone?

Ok. I managed to eventually open the textures within UE4 editor. First I opened the color map texture of the female version of the MilitaryLight Character. That opened ok, then subsequent textures seemed to be ‘openable’ one by one. I left the Diffuse textures until last, and although they took a little while I could open those too. I created a new material and applied just the diffuse texture to it , and this seemed to work ok on the mesh. So with very roundabout steps, I’ve managed to get past the issue.
