What happens if I delete shader file of new model?

[syainkn]

I've downloaded 'Vibrosword Bundle' in JKhub and applied in my game.

With new models, I couldn't load vjun3 level. In short, that level won't begin. I was stuck in loading screen.

But when I deleted shaders of models, I could load vjun3 level. The problem I suffered is fixed!

But I feel uneasy because of upcoming error. Is it right to delete shader files?

If unknown error occured due to removing it, What should I do?
