Frequently Asked Questions
Can I switch from Pro to Studio mid-cycle? Yes. Your remaining Pro days will be prorated and applied to the Studio tier. Enterprise onboarding typically takes 3-5 business days.
Do individual pack purchases count toward my monthly quota? No. Standalone packs like "Volcanic Basalt Set" or "Mid-Century Upholstery" are perpetual licenses and do not consume subscription downloads.
Are textures optimized for real-time rendering? Every asset is baked for PBR workflows in Unity URP/HDRP and Unreal Engine 5. Albedo, roughness, metallic, normal, and AO maps are provided in EXR and PNG formats with optimized UV layouts.
Is there a free trial for Pro? The Free tier operates as a permanent sandbox with 150 materials. You can upgrade to Pro anytime to unlock the full catalog without losing your workspace settings.
