Today we have received a 2000 $ donation from ACCA Software, which is an international company specialised on solutions for engineers, architechs and the construction industry. YafaRay is used as a render engine for stills in their BIM software called Edificius. We are proud to work with them because it makes real our motto about reaching lot of users with free raytracing (free as in freedom) and there is a real two way collaboration and feedback about improving YafaRay with professional input. Besides, this donation means a lot to our development team. Thanks !
