Flat sun.....
 

My sun in SH4 is flat, no lighting....im running TMO and PE4. It doesnt matter which mods are enabled, the sun is always only a white circle.

Sorry if I missed a fix for this or something, been away for a while.....

You're probably missing the 'SunHalo' file.
I think this is a dds file in the environment folder
:)

for nvidia cards, check for gamma correction off,
if you have an older ATI card you're out of luck

thx @ all

SunHalo.dds is present in SH4 and all the mods. My graphics card is a GeForce 9800 GT and gamma correction was on. However, turning Anti-Aliasing from 8x down to 4x fixed it, dont ask me why.....

What ver of TMO are you running?

I don't think you can run PE4 over TMO1.7.

I think TMO1.7 uses Env5 by WClear anyway.

I would disable PE and see how TMO works for you alone. If you want an env mod use the new Real Env mod. Seems to work fine with TMO.
