Please open a bug report on our github. Include steps to reproduce or even better a zip of workspace with this problem. Thanks!

Please add a trigger block that will allow you to create holograms.

Holograms is not a standard system in the game at this time that could be extended

Yay!!!
Now please update Forge to later version I BEG YOU!!

just checked and while items support custom 3d item models in hand and in inventories, the blocks do not. the only option for blocks is to choose an item texture, this should also include a item model to select for the block for inventories and in hand.

For this specific edge case, disable block item and instead make custom 3D model of item and place the block on right click of said custom item

FORGE 1.21.4 PLEASE :(

does this have support for 3d item models for blockbench modded entity models or just java block models?

Items can use Java entity models in 2025.2 already

What is meant was if I have a block made with a modded entity model using blockbench if I could use the 3d model for that blocks item instead of just a 2d image and if so how?

Yes, you can use it. Import java model and select it as item model. Similar as it is with JSON or OBJ models basically. I suggest you check our tutorials collection playlist on our YouTube channel which contains many examples and tutorials that can help you get started with MCreator: https://www.youtube.com/playlist?list=PLAeL-oIFIEngE6jRgFYeFMfuj8WQsO3Ei

will this add new bedrock stuff?

We don't publicly disclose feature roadmaps as they tend to change a lot due to free and open source nature of the project. Thank you for understanding.

Will this update have armor trims?

Armor trim support, that is

We don't publicly disclose feature roadmaps as they tend to change a lot due to free and open source nature of the project. Thank you for understanding.
