TouchDesigner on the EX range
The EX range supports the TouchDesigner RenderStream plugin only via the RenderStreamLocal layer. This is enabled with the optional EX Real-Time connector (RTC) license, which also enables a user to run a Notch block on the EX range. The Real-Time Connector license is purchased as a one-time cost. There is no need for a RenderStream license to enable this functionality. TouchDesigner using the RenderStream layer (where the RenderStream workload is deployed to an RX server) is not supported on the EX range.
TouchDesigner is the only RenderStream plugin type which is enabled on the EX range, provided the correct license is added. To use RenderStream integrations other than TouchDesigner, a VX or GX range media server must be used.
