Hi glisco,
already having fun creating beautiful renders with your mod.
While rendering larger natural areas, I noticed an issue.

Foliage colors don't seem to apply to tall grass and tall fern (double blocks).

Steps to reproduce:

• /give @s tall_grass
• Place it down
• Stand in it and use /isorender area ~ ~ ~ ~ ~1 ~

➡️ The rendered block will appear gray.

Eyo, thanks for reporting!
This is actually a known issue rooted in the nature of how multi-block scenes are rendered right now and bound to be fixed in a soon-ish update. I was first made aware of this about a week ago and actually wrote the exact code I need to fix it in a separate spin-off mod today. I'll integrate that into isorenders probably within the next week or so. I'll leave this open for now as a reminder for me to actually fix it
Cheers

Fixed in latest commit, build available on Discord (or CF as soon as that's back)

Great, thank you. Works perfectly with the new commit ;)
Unlikely to join the Discord though, I'm already on way too many servers

Alrighty, glad it works 👌
