Thank you for your reply, it's really helpful.

Hello Kirill and thank you for your welcome.

I have found what caused this problem.
At first I thought it might be caused by "_" in the name of the picture, but after I did some test, I found it wasn't the reason.

After that I found something. When I use a picture, it will generate a mctx0x document, it's usually so big. Especially in the use of HDR, the document will be as large as 600 MB. If the document was only 0~100, 100~300, 300~500 MB, it might be black, green or red. In short, it will have something wrong. I haven't thought my hard disk partition is full before I check it today. If there's not enough place in hard disk partition, the mctx0x document won't be created correctly.

I will keep rendering with CentiLeo and look forward to seeing it perfect someday.

Best regards,
Luey

hello, when i use centileo in C4D, i feel it's so cool, especially some meterial of transmission are really beautiful.
recently i used some hdr pictures in Envmap, but a few of them seem to have something wrong, some of them are just black. and other hdr pictures in use are fine.
i wrote an email to the address in "contacts". i am sorry to bother and maybe mailbox is not a correct place to discuss for users.
looking forward to see centileo better!
