If I read it correctly, Grimreaper has installed the beta into the C8 folder,. that’s the only way you would get a conflict,
As long as the programs are installed into differently named folders, then there’s normally no issues,
for example,. I have C6, C7, C8.1, and the C8.5 beta (32 bit and 64bit) installed on my system.
The only issue with the first releases of the beta was the shared “preferences file”,.
The beta now has it’s own preferences file in a different folder. so, unless you install the C8.5 beta on-top of your C8.1,.. you should have no conflicts.
The only way to resolve this is to remove both programs, and get back to a clean slate, then install them again, into their own (unique) folders.
They should do this automatically when they install,. but it is an area where the user can choose “where” to install,. and that, for some, can be confusing,... for example,.. thinking that the 8.5 beta is an Update for 8.1, (which it’s NOT)
As for the hair textures issue,. I don’t have that hair,. but the materials should be in duf format.
Have you tried jumping into DS4.5 and saving a Material preset (DUF) and then importing that onto the hair in the beta. ?
Also,. the format’s which the beta can use are still being worked on, and the meta data is being tweaked to provide a better smart content experience in carrara, so, products with issues will being updated.
Last resort is to jump into the shader room and load the textures manually, then save them as presets in your My Shaders in the browser.
hope it helps
