Frequently Asked Questions
Greyscalegorilla & Cargo 3.0 Integration
What is happening to Greyscalegorilla Plus?
To provide a more streamlined, powerful experience, the Greyscalegorilla Library is moving into Cargo 3.0.
New Greyscalegorilla subscriptions will now provide access to our massive library of HDRIs, Textures, Materials, and Gobos directly through the Cargo 3.0 interface. As a result, standalone Plus subscriptions are no longer available for new purchase.
Cargo 3.0 Supported DCCs
Cinema 4D: Mac + Windows
Blender: Mac + Windows
Unreal Engine: Mac + Windows
Houdini: Mac + Windows
Maya: Mac + Windows
3ds Max: Windows only
I am an existing Plus subscriber. What happens to my access?
Don’t worry, nothing changes for you right now! If you have an active Greyscalegorilla Plus subscription, you can continue to use Greyscalegorilla Studio and the HUB just as you always have. Your current workflow remains fully supported.
And, your Plus subscription provides access to everything in the Greyscalegorilla Library through Cargo 3.0, including expanded DCC compatibility. Just install Cargo 3.0 and connect your supported 3D software
What is included in the new Cargo-based Greyscalegorilla Library?
By accessing the Greyscalegorilla Library through Cargo 3.0, you get the best of both worlds in one unified Combined Library:
Complete Material & Texture Libraries: High-resolution, production-ready surfaces.
HDRI & Lighting Presets: Professional lighting environments.
Gobo Collection: Creative light patterns for any scene.
Universal Compatibility: All assets have been reprocessed into the USD format, ensuring they work seamlessly across Blender, Maya, Cinema 4D, Houdini, and Unreal Engine.
NOTICE: Plugins are on the way! We are hard at work adapting our most popular tools to live within the new Cargo 3.0 ecosystem.
At this time, Greyscalegorilla Plugins are not available for purchase.
Can I still use the Greyscalegorilla plugins?
Greyscalegorilla plugins are not available in Cargo 3.0, yet.
New subscriptions include access to Materials, Textures, HDRIs, and Gobos but do not include access to plugins.
However, plugins are on the way! We are hard at work adapting our most popular tools to live within the new Cargo 3.0 ecosystem.
If you require specific Greyscalegorilla plugins (like Light Kit Pro or Signal) through the HUB, these remain accessible to our existing Plus subscribers.
Why the move to Cargo 3.0?
The move to Cargo 3.0 allows us to offer much deeper integration and faster workflows. With features like Smart Search (searching by "emotion" or "intent") and Image Search, finding the perfect material or HDRI is faster than ever. Plus, the USD-native workflow means your assets will look and perform beautifully across almost any 3D software.
Purchases and Renewals
I just purchased a Plus subscription and it still says I don't have an active subscription.
Please go to this link and log out and log back in. Restart Studio and HUB after logging in and out of the website. If the issue persists, please make sure you are using the email you used to purchase your subscription and that you are using the latest version of each plugin and connector.
My OTOY coupon code says invalid when I try to use it.
The OTOY coupon for 2025 has expired. We are unable to redeem the 2025 OTOY codes for a free subscription to Plus.
I need a refund on my subscription renewal.
Our policy is that we do not refund monthly Plus subscriptions or annual Plus renewals.
Our 30-day refund policy only applies to new annual subscriptions. However, if you have an annual subscription that has renewed and you email us within 72 hours of the transaction, we will consider a refund.
Studio and HUB Support
My Light Kit Pro isn't working correctly.
We pushed an update to the Light Kit Pro plugin recently. Please go to the preference->At the bottom of the preferences window, click "open preferences folder">plugins> Greyscalegorila...then delete the Light Kit Pro folder. It will then be available for download again in the HUB with the updated version.
Some Troubleshooting tips if Studio/Connectors are generating error messages when connecting or sending materials to your 3D software:
Make sure that you are using the latest version of Studio (1.5.1) and connectors (1.5.3 or 1.5.4)
Please double-check to make sure that you have Studio and the connector installed in the appropriate folders. (instructions here)
Go to Edit>Preferences>Greyscalegorilla>Studio and make sure you have checked the appropriate boxes on how you would like materials to be imported and stored in C4D
For some users, you may need to update your computer's permissions settings to allow the plugin to function correctly
Does Studio support Unreal Engine 5.7?
Yes, but only on Windows. Make sure that you are using Connecter v1.5.4.
