Thank you, Froyok,
but a couple of issues remain.
I'm working on the XTAON Art Car competition, and SP (iRay) keeps ommitting colors and textures which have been assigned to textures. That is the colors and textures show in the SP UI, but when I try a test render one or more texture zones remain neutral gray insted of showing the assigned colors. Sometimes, in a texture, i.e. one material shows, but other regions of the same texture show gray.
I double and triple checked if the materials are activated in the materials layer stack. And they are. I also updated all ressources, problem still persists. The suppressed materials change, sometimes one or several show, others are missed. Then after returning, trying all kinds of stuff like de-activating and re-activating materials and/or layers, when I do a test render again, now one of the formerly missing metarials shows, but another one is missing which had been present before.
I'm appending the new log file, since I made the changes you suggested and updated ressources. Don't know if it helps to track this bug down. I will now re-install the former version and start todays work from scratch.
Also, Substance Painter has become slow, reacting sluggish, the former version 2.3 worked flawless, in comparison with the update.
I am very unhappy, just like I had feared, the work done and tried in the updated version 3.0 is now lost, I need to roll back again and start the finished work from scratch, because the project will not be compatible with the former version. This is really bad. I'm seriously frustrated. Will definitely not update ever again to a first update version. Next time you guys release an update, I will not even try it, will wait for the fixes to be released first. This is not a good and professional product policy for a software, to rush with updates, run customers into problems, and come up with fixes later. It can happen once and will be forgiven, but making it a habit is not a wise thing to do. I'm running dozens of softwares which are all updated from time to time, but the one I really fear to update has become Substance Painter.
Sorry to say this, it is just my personal humble oppinion, and I'm talking as a true friend and supporter of Substance Painter for almost 3 years already.
