Hello guys, i’m new in Cinema 4d and I need help.
i’m replicating one tutorial and I need to use the Texture Mode (i can’t use youtube links apparently)
My problem is: the yellow grid not appear!
Someone help me, please. I’m desperate
Thanks for your attention!
This short tutorial below shows the steps you need to ensure you do to see the yellow grid including, selecting Texture Mode 
, then clicking on the Object in the Object Manager.
The other thing that might be the problem is that you are using UVW Mapping on your material and therefore Texture Mode is not applicable. If so, change the Texture Projection to (as an example) Cubic and the Projection Display to Grid. See attached screenshot:
