The UI issue should be a completely separate issue than the preset mane issue. I will address both.
Your UI Problem
How to change the size of your UI: Go to C:\FeralHeart\ogre.cfg and open the ogre.cfg file in Notepad. You should get something that looks like this: Render System=OpenGL Rendering Subsystem
[OpenGL Rendering Subsystem]
Colour Depth=32
Display Frequency=N/A
FSAA=4
Full Screen=No
RTT Preferred Mode=FBO
VSync=No
VSync Interval=1
Video Mode=1600 x 1024
sRGB Gamma Conversion=No
[Direct3D9 Rendering Subsystem]
Allow NVPerfHUD=No
FSAA=None
Floating-point mode=Fastest
Full Screen=No
VSync=No
Video Mode=800 x 600 @ 32-bit colour
sRGB Gamma Conversion=No
What you will need to do is, under the [ OpenGL Rendering Subsystem ] section where it says "Video Mode= (width resolution value) x (height resolution value)", change those numbers to a high value. I would recommend trying 1024 x 768 to start out with. You can increase these numbers as you go along and even change them in the ingame settings menu if you would like. My 1600 x 1024 resolution is one that I customized myself. Save the file and run the game.
Your Preset Mane
What software are you using to save your .png mane file as? I have experience with Photoshop but I can try to help you further from there. It sounds like you're doing everything correctly but there might be a silly goof somewhere in there.
I tried both Photoshop as well as Paint Tool Sai, both times it did the same thing. I'm not sure what in the world caused it, but something is giving the mane issues xD
Oh, I apologize if I should have addressed both issues in separate threads, I will have to keep that in mind next time there is an issue if so o-o
When ye did this, were ye sure to delete all FH related files before reinstalling? Leaving files on y'er computer can be all that it takes to reintroduce the problem to y'er newly installed FH.
If ye did delete all the files before installing, try running the game as administrator. Ye can also change the rendering system by going through the main FH files and finding the file ogre.cfg. The first two lines are where ye can change y'er rendering system from OpenGL to Direct3D9.
Hope this helps!
I did change my rendering system and such, it was Direct3D9 when I first opened it up after re-installing, but I prefer OpenGL, though it's giving me issues with the preset mane when I have it like that, not entirely sure why, and running as administrator didn't make a difference, I do appreciate the response though, I'll double check the file in which you said as well. All files were deleted for reinstalled.
