There is an NDVI custom transformer

Good!

But the NDVIre is another index.

It is not the same as NDVI.

I need to create the calculation.

Hi @mr_fme 

the types of bands do not matter. All that matters is that you need two bands and some math with it. You can use NDVICalculator directly if you send IR to Infrared port, and Red Edge - to Red. Or, you can open the transformer and copy the expression from RasterExpressionEvaluator_2 - this is the transformer that does the actual calculation. Red goes to A input port, Infrared goes to B.
