Is there any way to use multitexture in version 4 (ex. wood floor) or the feature is limited to version 5 users?
You mean the MultiShader? It was introduced in Corona 5 as a feature, so you need Corona 5 or newer

Or alternatively, you could use Cinema’s variation shader if you aren’t planning on upgrading.
Finished school and missed 25e for one year, but still not working to afford full v5, wich i will buy for sure, now just learning corona for c4d with free demo v4. Thank you for answers.

There isn’t a free version for Cinema 4D, so not entirely sure what you have there…
