Can you confirm whether;
1. You are trying to display this Scaleform texture on a 3d object via a material? and
2. The setup works as intended, displaying on the object in 5.3?
Everything else should be default (0) unless you have multiple meshes on the same entity and/or multiple sub-materials on a mesh.
Thank you so much for replying to this.Your reply would be helpful for many people like me who are interesting CRYENGINE more than other engines.Yes I'm trying to display it on a 3d object and as you said I recognized my fault because I used a 3d model of TV for this scaleform material and it has few submaterials.
However I moved to CE5.2 and it is stable more than 5.5.2 because I don't know why 5.5.2 crashed several times but 5.2 didn't yet.I found the official tutorial video for scaleform on cryengine youtube channel and as I remember right now video lecturer showed it using CE5.2 without any errors.And it is working on mine like the tutorial.
