If you don't post more concrete information with your question, I am just going to ignore this thread until you do. I am not going to waste more time making further incorrect guesses about what you are doing (like they were the same entity type) only to give you more incorrect/irrelevant answers.

This is not a teach me how to mod forum. It is a support forum. You need to show what you have tried that you think should work. Preferably with the minimum amount of code on github so we can reproduce your problem. If we have to waste time asking for that information, we probably won't, instead your question will likely just get ignored unless the problem is obvious from the small amount of information posted. Anyway, the answer to this vague question can probably be found by comparing your code with Zombie.finalizeSpawn() or one of the other vanilla entities that can spawn multiple types?

Please don't post logs in the forum, use a file sharing site. There is no error in what you posted, if it really is the full log, post a link to the launcher_log.txt from directly after the crash.

That error does not say which mod is causing the problem, but it is likely one of the mods underlined below Check you have the latest versions then contact the mod authors.

Post the logs/debug.log to a proper file sharing site.

You need to give it more memory.

You know this question has been asked and answered "a million times" before in various forms in this forum? Along with all the potential "gotchas" that people commonly get wrong. Anyway: For the vanilla animations there is Item.getUseAnimation(). For the bow you will also need to understand ItemProperties https://forge.gemwire.uk/wiki/Item_Properties and how they interact with model overrides. This is the vanilla bow model: https://github.com/misode/mcmeta/blob/assets/assets/minecraft/models/item/bow.json Or here's some mods on github that reference UseAnim.BOW and so might similar to whatever you are trying to do? https://github.com/search?q=UseAnim.BOW&type=code That should be enough hints on what to research? Ultimately, you would be better off looking at ItemInHandRenderer and ItemRenderer (then following the rabbit hole) to see how all this fits together. Finally, this is a support forum not a learn modding forum. Questions like "can you tell me how to", "do you have an example", "insert question answered on wiki" will likely just get ignored. I only answered this question because it is your first post, I very nearly didn't. Come back when you have a problem with something you have actually tried to implement. That way you will also have a better chance at understanding any answers you do get.

Post a link to your logs/debug.log

Issue with immersive portals, contact the mod author. I would guess immersive portals doesn't work with optifine?

That error means one of your mods hasn't registered it entity renderer properly. The error does not say which mod or entity is causing the problem. Usually the only way to find it is to experiment with removing mods until you find the problem mod. Use a backup of the world to test removing mods. I can also see one mod (underlined below) modifying code in this area that might be causing it?

Remove that java 8 or update it to the latest version. Your error is caused by java trying to connect to mojang's website but it cannot validate the website is who they say they are. That old java 8 version contains trust certificates that have long ago expired.

Use java 17

Use 17

Override Blocks.canSustainPlant() e.g. https://github.com/search?q=cansustainplant+language%3AJava&type=code&l=Java

-Xincgc is a configuration option for older versions of java - it is not supported by modern versions You need to speak to whoever provides your launcher and/or check your launcher's java config options to understand why it is trying to pass that value.

Sorry, you are right, I think that is part of rubidium.

Could be. The error does say say if it is a file that is wrong or if a mod is processing a file incorrectly.

The error does not say which mod is causing the problem, but it is likely one of the mods I have underlined. Check you have the latest versions then contact the mod authors.
