I found an issue with the Extra Grain streaking module which does not provide a good preview when using the grain size parameter. For that reason I updated the module. To make sure that your existing presets using the extra grain streaking are not broken I added all the streaking types with version 2 into the same streaking module. This allows you to easily switch between Extra Grain and Extra Grain 2 (simply right click on the streaking name and select one out of the eight types).
To get the updated streaking module, simply download it from the exchange, it will override the old version.
