Ah, thats an easy fix. I had not bothered opening the patches due to other priorities but if its just a constant issue, you can say
const typeDef xxx; typeDef yyy = xxx; clamp(yyy, 0.0, 1.0) (or whatever the values actually are) Just assign a new variable to the constants value and replace all mentions of the constant with your new one (where it causes issues). Good catch, this should be an easy fix then to get those working properly. On Mar 31, 2010, at 1:26 PM, Steven Watkins wrote: > Hello, > > Ah good that sounds more promising.
