Feature Requests & Plans

What features do you plan to implement in the future updates?

We have a long list of small to large features and improvements we would like to implement.
We would also like to optimize Rebelle as much as possible for faster painting speed and better memory usage.

You are welcome to post your suggestions, ideas and feature requests to the Community Forum.

Do you plan to increase brush size?

We would like to increase the size of Rebelle's brushes in the future. We continually work on the software's optimizations that are necessary for enlarging the brushes.

Do you plan to implement salt, vodka, salt water, water cement, rubber, scraping paper, etc.?

We have a plan to add many special features which are used in painting process. Our watercolor simulation running behind allows to use different creative real or fictional mediums.

Will Rebelle be available on Mac App Store?

We have no plan to release Rebelle on Mac App Store.

Image, Painting & Pen Pressure

Is there any way to increase the default resolution from 29.7cm x 21cm 200DPI?

You can set your canvas size in the menu "File"->"New...". The maximum canvas resolution depends on your computer memory.

Rebelle brush is lagging with a larger canvas, why is that?

The math running behind the painting process is quite complicated, so for larger canvases, it would be always better to have a faster processor.

The watercolor diffusion is fast, is there any workaround?

The speed of watercolor diffusion depends on the amount of water on the canvas. You can pause the diffusion anytime with the "Pause Diffusion" button, or if you are satisfied with watercolor results click "Fast Dry" in the Layers panel to dry all water on canvas.

Does Rebelle support pressure sensitivity and touch features on Microsoft Surface tablets and Surface Book?

Yes, Rebelle supports Microsoft Surface touch features with pen pressure sensitivity.

The old Rebelle version (1.4 and lower) needed a N-Trig WinTab driver installed for Surface tablets. In any case if you need the WinTab driver: You can find the driver for Surface 3 here and for Surface 4 here by clicking on "Download". It's listed at the bottom amongst other Surface Pro drivers (
It is also recommended to use the Microsoft Surface Hub to set the correct pressure.

Purchase, Registration & License

My Registration Key does not work.

When you purchased Rebelle 1 and Rebelle 2, you were sent a registration key. If the registration key input text box in the registration window is red - it means that there are more letters, than needed. Please copy & paste the registration details you received as sometimes it happens that users misspell numbers with letters and vice versa when entering the key manually.

Why was my credit card declined?

Unfortunately, when the payment processing company declines a transaction on behalf of your bank or card issuer, it does not tell us why.

Your card may have been declined by your bank or card issuer for a variety of reasons; common reasons include:
- Incorrect credit card number or expiration date
- Insufficient funds
- Some banks will reject charges based on their own fraud rules

You will need to contact your bank or card issuer to find out the specific reason your card was declined, since they are the one declining the transaction.

You may re-attempt the transaction or choose the “PayPal” Payment method. You don’t need to have a PayPal account - after you click the “Checkout with PayPal” method, you will be given a choice to “Pay with a credit or debit card”.

How many computers can I install a single license of Rebelle on?

You may install Rebelle on multiple computers provided that not more than one of those computers is in use simultaneously and that those computers are solely for your own personal use. Rebelle may be installed on a computer that is for multiple users but it may not be installed on more than one computer regardless of whether those computers are operated simultaneously or not.
