Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

So you create a new material in the content browser, double click it to open its graph and what exactly does not work there?

Is there anything specific in the spaghetti up there that you're having problems modifying?

yes, the spaghetti is empty always, I try to modify a material that I had in my other pc. I give double click and it appears empty. For example "gold material" I can use it in the principal editor, but I give double click in the material to modify it and the spaghetti appears empty.

the spaghetti is empty always

I do not understand. You either see the nodes or you do not.

Also, in the original post:

And I tried to create a new material, neither work. Who can help me!!

You cannot create new materials?

No, neither. I cannot modify or create.

Could you elaborate please? What happens exactly if you do the following in the content browser:

Once created, double clicking it should produce this:

I tried to put some color: alt text But when I clicked in accept, nothing changes and the same happens with all thing that I've put in spaghetti. alt text

yes, of course that I know that I have to connect the nodes, but nothing happens. Simply the vector doesn't changes, if I try to change it, It doesn't change and It's always in black color. I'm going to reinstall the program.

Judging by the picture you uploaded, you set the colour to black. The right hand side slider is still at the very bottom. The RGB reads 0,0,0.
