FAQ

Q: Can I use this in my mod pack?
A: Yes mod packs are fine please link to the curse forge page through.

Q: The mod lags a lot why?
A: The mod requires a fair bit of memory, and CPU power to run. It's not designed for lower grade computers.

Q: The time does not match the current time why?
A: This could be of one of two reasons, first Minecraft shifts the time over by 6 hours the mod takes this into account already but if your looking at the ticks this would be the reason. The other reason could be if your playing on a server, the server time could be hosted elsewhere which the computer time would be a different time. We have a game rule that can offset this time in that case.

Q: Can you add support for X mod?
A: Most features if not all features should work with all mods automatically without adding support. We will leave it up to other mods to add support as most things are data driven using tags.

Q: Can you add X feature?
A: If you share your suggestion on our discussions page on GitHub we may add it in the future.

Q: Is the mod laggy because of MCreator?
A: No, this is due to having to run much of the system on tick updates which requires more memory to do. MCreator does not have any responsibility over this directly.

Q: Can I repost this mod?
A: No, it's all rights reserved, we don't consent to this.

Q: Will you support NeoForge X.X.X?
A: This depends what MCreator ports to mod creators have no control but we do plan on porting this mod.

Q: Will you add support for Forge X.X.X?
A: No, forge is a dying platform, most mods do support NeoForge these days and MCreator dropped support a few updates ago so we won't support this in future versions.
