Probably the same issue as:

All of these should be fixed and closed by Iris 1.8

If the shader pack still doesn't work after upgrading to the Iris 1.8 beta, please send your full log file

Usually this is found at .minecraft/logs/latest.log. If you are not sure how to find .minecraft, please see this article: https://minecraft.wiki/w/.minecraft#Locating_.minecraft. Please do not upload a compressed (.log.gz) file, they are very difficult for us to read when viewing issue reports. The log file instantly tells us important information like the versions of any other installed mods or if there are errors so it is very very important that you include it in your report.
