The log is cut off.

The log you sent isn't the full log. Can you please send the full log or a crash log?

Well, I can't help you further because I checked the log again and saw that it is 1.10.2. We don't support 1.10.2 anymore. I know this is the off-topic channel, but I don't know which rules apply where so... ¯\_(ツ)_/¯

It only took me about 30 seconds, but it seems like CustomMobSpawner is your issue.

I can't seem to be able to find Qmiscutil on the internet. Can you send me a link to it?

I suggest opening up some of the various morph mods out there and seeing how they do it. I don't think it's that complicated, unless it requires mixins (which are complicated until you know how to use them).

Can you tell me what mods you are using?

You need to change the share permission to public.

You can upload them to Imgur or Google Drive and then click Insert image from URL. Like this:

Try sending the crash report.

What are you trying to do?

Make sure that it only happens with forge. Try Fn+F3.

I looked it up, SK-Launcher is a cracked launcher. We don't support cracked launchers and will not help you with it in the future.

I think it's just a bunch of Java path stuff I really don't know how to do of the top of my head. You will have to Google how to change Java path or how to downgrade Java.

The mods you are using use Mixin. You are using Java 19. Java 19 breaks Mixin somehow. You must downgrade to Java 17.

Can you send the crash report? Crash reports are usually very helpful and most of the time say exactly what mod caused the problem. Also, you should note that throwing 226 mods together all at once is a very bad idea because if you get a crash, it is VERY hard to find which of the 226 mods caused the problem. Also shoving mode mods into it won't fix the problem, if anything it will make it worse.

Try reinstalling forge. Is this on curseforge? What is it on?

You can use net.minecraftforge.client.ICloudRenderHandler to modify cloud rendering and net.minecraftforge.client.IWeatherRenderHandler to modify rain and snow. You might want to look up examples and usages for more information because I cannot be of any more help here.

1.16.5 is no longer supported here (just 1.18.2 and 1.19.2). You will have to ask reddit.

1.16.5 is no longer supported here. We only support 1.18.x and 1.19.x.

The problem is that 1.16.5 is no longer supported on this forum. You will have to ask reddit (and post your crash log along with it).

Java 19 does not support mixin. You must downgrade to Java 17.

Therefore, you should also know that 1.12.2 is not supported here. (Just 1.18.x and 1.19.x)

This is a java problem, not a forge problem. Try other methods of launching jar files and make sure you have a compatible version of java.

Does this work in an empty dev environment? It might be your graphics drivers.
