First of all, the way this forum is designed SUCKS. If you type a bunch of stuff in this field and then change the "Conversation Type" radio button above, it erases everything. Brilliant web programming Adobe.
Now, is there a way to change the color or properties of the default material? If not this is ludicrous. This material shows as a glossy white material, which is a real pain the ass if your model also requires a similar material to actually be created on parts of it -- a situation I am currently dealing with, with a very complex model with a lot of small parts. I need to be able to see at a glance what has been painted and what hasn't.
Yes, I KNOW I can go into "Base Color" mode, or create a colored fill layer at the bottom of my stack. But these are both inconvenient workarounds, and the latter simply adds bloat to an already large project file. There should be a way to either turn off the default material completely in fully shaded mode, or change its color to something obvious like bright red.
I'm not sure if i understood what do you want but i found you need your personal material which when you need it, you can add it fast.
for this subject you can do one of the followings:
1. make your personal material and just hit ctrl+D to duplicate it.
2. after making your personal material, click on "add group" (a folder shape beside new fill layer) and a folder will appear in layers, drag and drop your personal material(s) to the folder and rename folder. then right click on the folder and hit "create smart material". this step makes a smart material which you can always use the material from "Smart Material" tab.
